Corrupt JPG files?

I looked up this problem with the search, but didn't really come across any solid answers. I'm trying to open some JPG images from a CD. The CD was originally made on a PC. Weird thing is that I can open some JPG's and not others. There's one whole folder full of images that won't open. I get the "unreadable" error that says the file may be corrupt, etc. So what's the deal?? Could it be something with the way it was saved on the PC and now it can't be opened on a Mac? I remember checking these CD's after making them on the PC and all of the files opened just fine. Any idea what's going on??
By the way, I tried opening the JPG's in Preview and Photoshop and got the same error. I can't even get a thumbnail preview of the image.

Are you sure that all of the images have the .jpg or .jpeg file extension attached to the name?

Fixing corrupt JPG files

Is there any good software out there for fixing corrupt JPG files?

Corruption damage in a .JPG entails data loss and the JPEG format does not contain redundancy, so there's no way to recover what's lost. Usually if the damage is found towards the end of the file, you can "recover" the good part by truncating it. If you want to do it interactively, you can try using software such as [The Gimp|http://www.gimp.org>, or its (very) expensive brother, Photoshop.
To do it automatically (batch mode) you can investigate if any of the tools in the [Image Magick package|http://www.imagemagick.org/script/index.php] helps. Note that these are command-line Unix tools.

More jpg file corruption

I've had another jpg file corrupted in the same manner as before and this time the file hasn't been touched recently by anything but LR. My second copy was also corrupt because I "back up" too often. Fortunately, it's easy for me to get files back from my internet backup, which is written only once. To get to my CDs or DVDs would require digging in a closet.
To me this brings a lot of issues to the fore with jpg handling, both what I do with them and what LR does with them. First, if you are going to rewrite files frequently (I only write metadata on demand, not automatically) then you have to know how to do it safely! On my side, it may be stupid to write it out -- nope, not, because I have to in order to edit in PS and retain the metadata. I have almost innumerable LR backups and the metadata is in there. I have considerable experience now in plopping in an absolute original file and LR happily applies everything to it. Hum. I'm forgetting the PS edits which would not be backed up with this plan.
The existence of 1 to 1 previews makes it very slow to SEE a problem in LR. I haven't used these files for months until the 9th when I started working on them. The first day or so it was grinding a lot, obviously making previews. So the good preview of this file had to be made on the 9th or a bit after so the file was OK at that time. In fact, everything looked fine until I decided to edit a copy of the file in PS. It stumbled and flickered the screen and then created a preview with only the top third or so of the file intact and the bottom part "faded." These appear to still be (almost) valid jpg file, but the content has been damaged.
I have used jpg files for years and I don't remember a time when I've had jpg file corruption. I may have forgotten an instance, but it doesn't come to mind. I've had 3 or 4 them now with LR.
These jpg files were created from scans and I have manipulated them to put the capture date, date digitized, and some global type information. I use exifer, a product that's been used for many years by many people (and not updated recently). If exifer is a problem, why only a handful of corruptions in thousands of files?
It's difficult to have a sensible backup plan except to keep the originals somewhere really safe. Even with metadata writing turned off by default, these files churn. I cannot keep every version of jpg files. And keeping the old files for a short period does not help because bad files don't show up in LR under many circumstances because of the preview files.
I don't know if this is relevant but I never had this happen with LR 1.0.
This is very worrisome and I'm going to get grouchy soon! You guys with RAW are really lucky that LR doesn't write to your files! I'd now love to have an option of a sidecar file which I could write to the jpg only when I'm ready to and have a way to check that the resulting file is still intact.
Of course I haven't proven there isn't an issue with my disk drive, but I've now proven it to myself that there's a very high probability that LR is corrupting jpg files when writing out metadata. I would like to hear if others using jpg files have had corruptions.

Hi, I too also have just experienced jpg corruption. It was a jpg that had been taken several years ago and had not been edited at all. The bottom left hand corner had been transposed from the right hand side. The result of this was the whole bottom 1/5 of the picture was shifted to the right. Also the color of the shifted portion was slightly different from the rest. This is the first jpg corruption in Lightroom I have seen. My backup was the same but fortunately I had a copy on DVD. I am using Windows version of Lightroom 1.2, tried 1.3 and decided to go back to 1.2
Does anyone know if this type of corruption only happens to jpg files. Would it be worthwhile marking them all read-only. I plan to check my other jpgs to see if there are any more corruptions. I mainly shoot RAW now and convert to DNG

JPG files become corrupt after Exporting in LR 3

Does anyone have any idea what would cause
my JPG files to be corrupt after I export my edited Raw images in LR3? There are no problems with the Raw file, but once I edit them, apply what ever settings to them in LR I need, I export them as JPG to the same hard drive but in a sub folder where the raw files are, they will not open in photoshop or anywhere else. They are corrupt or lacking data???? When I upload them to my proofing website, there are colored streaks all through the image. Now, I noticed that when I go into that folder of RAW images, and delete the .xmp files, I have to start over, but it fixes the problem. So, now, I can't use .xmp sidecar files to save my editing. I'm fairly new to LR, so any suggestions would be great. I did recently upgrade my system to OS windows 7. Everythign was fine till I had to reinstall everything on my computer...and I also changed hard drives. I upgraded to a Terabyte drive moving all my images from a 500G to the terabyte. Could that cause my sidecar files to be corrupted?????
Thank you!!!!!

I doubt that the XMP files have anything to do with this, as Lightroom doesn't use these files when it creates an exported file.
It sounds like your hardware may be the culprit; these types of corrupt files are often caused by a failing hard drive. Some corruption may have happened in the transfer from one hard drive to another; or the new hard drive has some sort of problem.
Can you hook up the old hard drive again and see what happens to the photos there? Open one of them and compare it to the photo on the new hard drive.

Bridge CS5 is Corrupting Raw and JPG Files Right Before My Eyes

I am using Bridge CS5 on a Mac to work on Raw files from a Canon camera. The files all looked good in the cameras review, and looked good when downloaded to the computer then the files started to corrupt and become unusable one at a time as I watched. They became all white or lines of color. Not all of them corrupted yhough (about 225 of 1100 did though). I eventually worked the uncorrupted files and even turned them into JPGs and sent them out. The next day I pull up the pics in bridge to see if they are still bad. All of a sudden files I opened and worked on yesterday started to corrupt one after another. Both the JPG and Raw files are corrupt and unusable even though they worked yesterday. It only happens when in Bridge. What is going on? This is riduculous.
Terry

Thanks for responding. What happens is I highlight a large group of files then click on open with Bridge or in Bridge I go to the subdirectory with the files. All the files are in a filmstrip on the left side of the screen. All of a sudden the file that I am viewing becomes corrupt (that is it turns into multiple horizontal lines of colors. Then I can watch as it happens to one file after another. I would compare it to when you quickly view film strips that were just uploaded and the initial thumbnail is blurry and then slowly all the thumbnails get clear as they process. But here they appear to already be fine thumbnails but then turn into the files with horizontal lines or sometimes just 30% or so so of the pic is visible and the rest is white or gray. When I try to open it the file cannot be opened because it is corrupt. It happens to both the RAW and the JPG file (I shoot in Raw+JPG). The first day it happened to about 200 of the 1200 files. So I was able to process the 1000 good ones in Raw convertor and create JPGs with no trouble. The next day I open all the files in Bridge again to see if the bad ones are good now and files I had already opened and were perfectly fine in RAW converter start to corrupt one after another like the ones did the day before. So I doubt it is the card or hardware it only happens in Bridge. Bridge must have the capability to do something to the files. It isnt making XMF files so thats not it, it is actually corrupting the RAW and JPG files. Have you ever heard of that. I found another forum with what sounded like the same issue to someone who had a Canon: http://forums.adobe.com/thread/645620
But this happened to Windows and I use MAC.....but I do use a 7D like them. I still wonder if Bridge just doesnt work well with Canon 7Ds or something like that. The above thread never found a solution. Maybe someone from Adobe has heard of this from others and discovered a reason or solution. Until then I cant trust Adobe products at all....which really sucks after how much it cost me, but whole shoots lost is worse, I guess.

Jpg files are becoming corrupt

I am a photographer with thousands of photos on my external hard drive. Over the past month or so, I have lost access to many of my jpg files. The icon no longer appears with a thumbnail of the photo... only the icon appears with the title of the file. I can't open these files with the Preview, and my Photoshop can't open them either. The message I get is, "Couldn’t open the file. It may be corrupt or a file format that Preview doesn’t recognize."
Questions:
1. What can I do to stop this from affecting more of my photos?
2. How can I recover the jpg files that are lost?

Leopard should be able to read and write to the Fat32 drive. However some programs like Aperture do not support Fat32. Not sure if that's also a problem then for Preview.
http://support.apple.com/kb/TA24491
Were you successfully reading and updating over a period of time and then noticed you had a problem with 'empty' files or has it been this way since you attached the PC drive to your Mac? If it just started happening, what were you doing with those files or any files on the drive? It may not be the files, but possibly the directory that is at fault and can't find the file content.
Just for your information if you ever add a new drive or reformat the drive to be the recommended Apple format, ensure it is partitioned GPT (GUID Partition Table) and formated HFS+ (Mac OS Extended Journaled). Of course you'll want to copy everything somewhere (do you have a PC that might successfully access the files?) to back things up before you reformat!

Bridge won't open JPG files in Photoshop CS3

I changed my preferences to remove the check-box "prefer Adobe camera RAW for Jpeg and TIFF files" , restarted Bridge and tried to open a JPEG from bridge directly into photoshop. But double clicking on the image in bridge opened "paint".
So I change the Bridge preferences back to Prefer ACR for JPEG again, restart Bridge, and then bridge tells me that it cannot find Photoshop CS2. CS2 is not even loaded on this machine anymore.
So then I go to the file type associations preferences and "browse" to the CS3 version of photoshop, restart bridge, and double click on a JPEG and it again says that CS2 cannot be found. I change the association again using the "browse" to CS3 and then it opens the image up in "Paint" again.
Why won't Bridge open JPEG's in ACR anymore?
Why won't bridge open JPEG's in Photoshop CS3 anymore?

Bill, thanks for the reply. But I do not think that the file associations is the answer here. If I am using bridge to open files in ACR or Photoshop, I do not believe that I need to change the windows file type association. I have other PC's where the file association is not photoshop and bridge works fine opening these files. In fact, when using windows explorer to navigate JPG files, I do NOT want photoshop being opened to preview these images. On my other PC's, I can both preview JPG's using windows picture viewer, and open the JPG's via bridge in ACR. Furthermore, Photoshop CS2 is NOT the application listed for JPG's in the folder options in the control panel. So the problem that I have here has something to do with Bridge or perhaps something is corrupted int he files.
The reason why I suspect a corruption, is that not all files behave in the same manner in bridge. Some files with the same extension open as I would expect, while others do not. I did not realize this fact when I made my original post.

Importing jpg files from hard drive

I am trying to import all my pictures into iphoto however am getting an error:
Unreadable file, The following file cannot be imported. (import failed).
The files I am importing are *.jpg files from various camera I have owned over 5 years. I have all the photos uploaded into my apple TV as well as being very easily readable through other picture viewers on my Mac. I cant seem to understand why it would not import into iphoto.
Please can somebody help me if you have ever had this issue before.

Welcome to the Apple Discussions. Try copying a few to the desktop and from there into iPhoto. If that is successful then there's something about being on the Apple TV drive that iPhoto doesn't like. If that's the case you may have to copy the photos to the desktop, import into iPhoto and then delete them from the desktop.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
Note: There's now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

Writing metadata to originals is corrupting my files.

Hey guys,
I am using Aperture 3.3 with 10.7.4. I am importing my files, but they are not being copied into the library. I am leaving them where they are. Next I add keywords to them and then use the command 'Write IPTC metadata to originals'. Doing this is corrupting my files. I am getting an unsupported file format warning in place of the files. When I go to the files in Finder, the files are junk. Thankfully I backup my photos before doing anything to them so no harm done this time.
Thanks
Jason

Hey Owen,
Thanks for replying. I just now tried again and the same thing happened. Now the first time I tried Aperture I stopped thinking something was wrong and I didn't want to mess up my files so I just continued using Picasa and iPhoto. This time I did the same thing, but came here and posted my problem. And after reading your reply I decided I probably should try some other folders full of photos. And guess what....no problems. It appears this one particular folder full of photos is somehow messed up and when I write the metadata back to the files they get corrupt. They are jpgs from 2000 and the camera was a Toshiba PDR-M3. Now other photos taken with this camera are working so it must be something with this set of photos.
Thanks again.

Elements increases JPG file size - case # 0181346249

I just asked this of Adobe. Couldn't find anything this specirfic in the forums, anyone have anything on this? Thanks in advance. Lee
~~~~~~~~~~~~
On/about 12/4/09 I upgraded Elements from 6 to 8. Since that date I have discovered that the file size for all JPG files managed by Elements has been increased by 5304, 5309 or 5310 bytes. This has complicated my backup scheme, now the backup program wants to replace all said files, in excess of 16,000 pictures.
What is Elements changing?
Is this documented?
The attached JPG shows the original file on right, the Elements managed file on left. The far right column shows the file size increase.

It may be that you have the Auto-Analyzer set to run automatically, and it has added some additional metadata (EXIF) to each of your files.
The PSE 8 Auto-Analyzer has some severe problems, and I recommend that you never run it. It will corrupt your map locations, split your video clips into "scene groups" that are hard to get rid of, modify the date/time of every file, crash frequently, make your computer very sluggish, and litter your folders with temporary files:

Corrupt cfmail file with ï»¿

Over the weekend I had an email hang up in my \Mail\Spool\ directory. ColdFusion would try to send the file but would just hang on it. It would never move it to the \Mail\Undelivr\ directory. In the Mail.log file it created a single entry that just displayed as "Error", with no other information.
In the meantime no other email was sent. The spool directory grew as new email was being spooled but ColdFusion would never get past sending the corrput file.
I opened the file in a text editor and the file began with the following characters: ï»¿
The email file looked something like this:
ï»¿server: mail.myserver.com
from: [email protected]
to: [email protected]
subject: Example Email
type: text/plain; charset=UTF-8
bodypart-start: text/plain; charset=us-ascii
body: Just an example
bodypart-end: text/plain; charset=us-ascii
This apparently was just a fluke because in the hundreds of email files I have looked at over the years this is the first time I have ever seen those characters displayed. I was able to get the email to send by deleting the characters and saving it back to the \Mail\Spool\ directory.
Searching the web reveals that those characters represent the Byte Order Mark (BOM) of the Unicode Standard. Specifically it is the hex bytes EF BB BF, which form the UTF-8 representation of the BOM, misinterpreted as ISO 8859/1 text instead of UTF-8.
What would cause CF to screw up createing an email file beginning with these characters?

Camera Raw updates Date Taken in JPG Files

Hi,
I have CS6/CR 7.2. I have had this issue where my file dates became changed (8000 odd files) so I had to restore 23000 files from backup .
When investigating trying to find out what happened. when I open a JPG from Windows Explorer, photoshop is set to use Camera Raw for jpg files on open (ok). If I cancel the dialog, nothing happens (ok). If I click Done or Open Image, the file itself has the "Date Taken" time updated - 7 hours ahead of the original correct time.
This pretty much matches the date issue I have on the 8000 files. Is this expected behaviour? Why would Camera Raw update Date Taken and did it choose 8 hours because I am in the PST timezone (GMT-8 or currently GMT-7 with daylight savings)?
I have reproduced this on 4 or file random files - taking copies and comparing afterwards.
Thanks!
Mark.

Camera Raw writes your JPEG files back out with updated metadata no matter what settings you choose, because Adobe feels they understand the format of metadata in the files well enough to be confident they will not corrupt the files.
I've asked them for years to avoid doing that, to no avail. I don't want my original files re-written. It sounds as though you are of a like mind.
It is for this reason that I *never* open a JPEG file through Camera Raw.
It's possible there is a time zone problem or something, but that's not the point. What, specifically, is corrupted is less important than Adobe believing it's okay to write back to your JPEG files. That you have actually seen something corrupted is testament to it not being unfounded paranoia.
Generally I'm supportive of Adobe's design decisions, but absolutely not on this issue. All I ask is that Adobe honor the "keep settings in the central database" preference choice for ALL input files, not just those for which they would otherwise write an XMP file. I don't think it's too much to ask.
By the way, you might want to visit the Camera Raw-specific forum and make note of your issue there:

Corrupt image files cause upgraded iPhoto to crash

I have been spending some time trying to find and remove corrupt image files from my iPhoto library. These are not just scrambled images when viewed they crash any and every program you view them with. Including Finder. I accidentally put one on my desktop and finder went into a auto restart cycle I could not stop. until I removed the file with pathfinder. I have found about 30 of these so far (my library is about 25,000) Many of these are in the data file but some are not. They are of all types (jpg,tiff,psd) Thorsten Lemke, (Lemke Software) tells me it is a quicktime issue.
Here is a link to one of these files. Warning it will crash safari if you try o view it.
http://vincentdavis.net/try/try.jpg
Here are my questions.
1. is there some way to fix these
2. is there some efficient way to find and remove/fix them?
3. how did this happen? I had no problem before update (that I knew of)
Thanks
Vincent

I did try the link, and as you said - it crashed Safari. However, I have google searched and also searched the Apple Support sites for 'fix corrupt images' with no luck. I'm sorry but I think the only way of knowing is to try and open each of them.
However, I did read on Macworld's site once that sometimes photoshop or other image editing programs can open the corrupt files.
Sorry for not being much help here - I hoped that my first suggestion would have done the trick.
