Missing thumbnail in some saved jpegs

After opening a camera raw image and saving it as a jpeg, sometimes I am missing the embedded thumbnail in the jpeg, and sometimes it's there. I can't figure out what I'm doing to cause this. Any suggestions?

It's the EXIF thumbnail which I read with an external program. I'm assuming it's something in the sequence I use to convert the raw image in Photoshop into a jpeg and then save it, but I can't figure out what sequence it is that causes it. When I save (or save as) the image the checkbox for "thumbnail" is checked but disabled (greyed out). ICC profile is turned on.

Need some help trying to generate thumbnail images from large Jpegs

Hello,
I have some ActionScript 3.0 code, created with Flex that
will load a large JPEG image (say 3000x2000 pixels) that I'm trying
to create a 100 pixel thumbnail. I have the code working where I
generate the thumbnail, but it's not maintaining the aspect ratio
of the original image. It's making it square, filling in white for
the part that doesn't fit.
I've tried just setting the height or width of the new
image, but that doesnt render well, either.
To see what I'm talking about, I made a screen shot, showing
the before image, and the rendered as thumbnail image:
http://www.flickr.com/photos/taude/533544558/.
Now, there's a few things important to note. I'm saving the
thumbnail off as a JPEG. As you can see in my sample application,
the original renders fine with the proper aspect ratio, it's when
I'm copying the bytes off the bitmapdata object, where I need to
specify a width and height, that the trouble starts. I've also
tried using .contentHeight and .contentWidth and some division to
manually specify a new bitmapdatasize, but these values seem to
always have NaN.
private function makeThumbnail():void{
// create a thumbnail of 100x100 pixels of a large file
// What I want to create is a a thumbnail with the longest
size of the aspect
// ratio to be 100 pixels.
var img:Image = new Image();
//Add this event listener because we cant copy the
BitmapData from an
/// image until it is loaded.
img.addEventListener(FlexEvent.UPDATE_COMPLETE,
imageLoaded);
img.width=100;
img.height=100;
img.scaleContent=true;
img.visible = true;
// This is the image we want to make a thumbnail of.
img.load("file:///C:/T5.jpg");
img.id = "testImage";
this.addChildAt(img, 0);
private function imageLoaded(event:Event):void
// Grab the bitmap image from the Input Image and
var bmd:BitmapData =
getBitmapDataFromUIComponent(UIComponent(event.target));
//Render the new thumbnail in the UI to see what it looks
theImage.source = new Bitmap(bmd); //new Bitmap(bmd);
public static function
getBitmapDataFromUIComponent(component:UIComponent):BitmapData
var bmd:BitmapData = new
BitmapData(component.width,component.height );
bmd.draw(component);
return bmd;

Dev is 10gR2 and Prod is earlier version of Oracle, 10gR1.
The schema (or table(s)) export file created by Oracle Database Control in Oracle 10gR2 is not importable into 10gR1, by default.
Workaround.
Use the Schema (table(s) export wizard of in the Maintenance section
of the Oracle Database Control in ver 10R2,
but when you get to the end of the wizard (I recall Step 5),
show the data pump export source PL/SQL code, cut and past to editor,
and find the variable where you can set the Oracle database version
to your prod database version,
then run the script from the SQL Plus prompt in 10gR2 dev,
and this creates an Oracle 10gR1 compatible data export file.
Then go to Prod and run the schema (table(s)) import data wizard,
and import the export file. You will have to option to move the data
to another schema or tablespace if required.
Just to not run into troubles, I use the same schema and tablespace name
in both dev and prod.
the variable you must modify in the 10gR2 datapump export script looks like
h1 := dbms_datapump.open (operation => 'EXPORT', job_mode => 'SCHEMA', job_name => 'ExportTableToProdJob', version => 'COMPATIBLE');
and you must change manually to
h1 := dbms_datapump.open (operation => 'EXPORT', job_mode => 'SCHEMA', job_name => 'ExportTableToProdJob', version => '10.1.0.1');
This creates a 10g1.0.1 or later compatible export data file.
You must have read/write privileges to the folder were the export data file will be created, and imported from. (Oracle Directory Object)

Missing Thumbnails in CS5 bridge

I just got Photoshop CS5 and for the first time decided to use Bridge that comes with Photoshop. My problem is that Bridge doesn't show thumbnails for all my files. Some folders of images have a few thumbnails missing, other folders have a lot of thumbnails missing. One of my folders have over half of the image thumbnails missing. An icon shows up instead. I can still double click these icons to open the image in Photoshop but I can't see the image in advance of opening it. I found a whole lot of info on the adobe web site concerning thumbnails in a lot of various products. But nothing seemed to match what I'm experiencing. In fact a lot that I read leaves me more confused. Anyone else having this problem and have an answer?

90% jpg
Some NEF and some TIFF. None of those have missing thumbnails, but then I don't have very many of each.
Just got an upgrade to Bridge this morning, version 4.0.5.11. After it installed I checked for a change in the thumbnail problem. No fix.
ACR is version 6.4.1.145

Missing Thumbnail Fix, at least for me

I had an extremely frustrating issue with missing thumbnails (dotted blank boxes) with iPhoto 6 that migrated to iPhoto 8 with no relief. I tried all the thumbnail and library rebuilding, and permission repair issues to no avail.
In my case, the original images were fine - if I double clicked on an image, it would open fine in iPhoto - right-clicking to reveal the original in the Finder worked fine too. But for about 100 photos, no thumbnails.
I finally discovered that if I edited the image in some minor way, the thumbnail would rebuild. The easiest was to rotate the image (selecting multiple worked as well), and then undoing the rotation. I don't know what caused the issue to begin with, but this action fixed the issue in a way the built-in rebuilding option could not do.
Hope this helps.

Tom:
To help prevent loss like you experienced see the tip at the end of my signature.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto 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 written an Automator workflow application (requires Tiger), 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 08 libraries. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Missing Thumbnails

Missing thumbnails
In October I switched from OS 10.1.5 to OS 10.4.8.
My thumbnails have become only dotted outlines in iPhoto 6.0.5, except when enlarged.
Reading thru these topics, I realize it may be my fault.
I apparently committed a no-know by renaming the folder that appears after the folders MODIFIED and ORIGINALS with a different name. What I think I have done is rename the THUMBNAILS folder.
I have no idea what that original folder name was, so can somebody supply the name, and will that help? I would like to try this before going to the other methods for restoration.
Luckily, I saved all of OS 10.1.5 on my new external HD along with those files, so I can go to the old iPhoto 2.0 anytime. The Thumbnails work just fine in 2.0, maybe I should not bother with all this c--p!
G4 Mac OS X (10.4.8)

IT WORKED!
Thanks for the advice Terence. When I changed that Thumbnail folder name back to "Data" from what I had named it, all my Thumbnails came back. The reason I stupidly changed the name was that I was looking for the folder that holds the album folders, and wanted to identify that folder by using a different word. I still have lots of things to work out in going from iPhoto 2 to 6, and will post more questions as I go along.
Thank you,

Saving jpegs or pdfs from aperture completely blown out since upgrade

since the upgrade to mavericks the saving on Aperture doesnt perform.
Highlights are blown out beyond recognition. Saving books ( pdfs to jpegs) - complete nightmare, can barely see the photo
Saving a jpeg - doesnt work - again highlights blow out picture beyond recognition.
You can see a vague outline of some of the picture but its like the luminence or exposure has been taken up 50 points.
I have noticed if i redit the photo from scratch then all if fine - but I cant do that with my workload - its like reediting a whole project - Anyone else got this stupid problem? Is there a CURE?

Saving books ( pdfs to jpegs) - complete nightmare, can barely see the photo
How are you saving your books? By printing the book to PDF?
Saving a jpeg - doesnt work - again highlights blow out picture beyond recognition.
And how are you saving jpegs? File > Export? And use a JPEG preset?
What is your Aperture 3 version, and what is your MacOS X version?
I suspect you are having a problem with a wrong color profile when saving your books or jpegs.
What is the color profile used in the Export Preset you are saving your JPEGs with? set the export Preset to "Edit" to be able to inspect the details.

Saving JPEGs in PS CS4

I've saved thousands of JPEGs in Photoshop over the years, almost always using the Save For Web dialog since that was introduced. On rare occasion I would use the JPEG format choice from the Save Dialog but not often. Today I was modifying a couple of JPEGs used for material mapping on OBJ files. I wasn't using the OBJ models in Photoshop just opening and modifying jpegs. On two of the files when I saved my changes the changes were saved without any further dialog. It seems to me that always in the past when I re-saved a JPEG there would always be a dialog to for the compression level and other encoding choices. Today the files were just saved without the extra dialog.
I like this saving JPEGs without making copies and the extra dialog as it saves a number of extra steps. I do wonder if this is a new feature of CS4 or whether it existed before and I'd just never run into it. Then I wonder if this is some selected setting of the JPEG dialog when they were first saved.

If you've saved the Jpeg already then it defaults to the last saved compression which is why so many say don't use Jpeg because you can destroy a pic with out knowing.
It only goes to the compression dialog if you Save As

Firefox does not load long images, pixelates images if they are not in their original size, and has problems with thumbnails (in some sites)

Firefox has problems with images.
In sites like deviantART or ImageShack with full-view option, images that are not in full size/thumbnails get slightly pixelated e.g. http://img251.imageshack.us/f/screenshot2tq.jpg/
Long images get completely messed up if full-viewed e.g. http://img689.imageshack.us/f/screenshot5z.jpg/ (though if the file is only big, it loads just fine)
Also, thumbnails in some sites get messed up e.g. http://img201.imageshack.us/f/screenshotyr.jpg/
And in general, Firefox has more 'glitches' like not allowing to add more search engines. It wasn't like that before and I can only assume that it got messed up somewhere with updates, but I'm not really sure.
I've tried cleaning out cache, re-installing Firefox (multiple times) and even downloaded Firefox 4 beta, but the problem remains.
I use Ubuntu.
Does anyone else have similar problems? Or know where the problem lies?

Do you have the latest driver for your graphics display card?
Create a new profile as a test to check if your current profile is causing the problems.
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

I just upgraded to iPhoto '11. When it was finished many pictures do not appear. I have a black box but the information for the picture is still there. Some are raw and some are jpeg. Also lost all albums. Can anyone offer assistance?

Apply the two fixes below in order as needed:
Fix #1
1 - launch iPhoto with the Command+Option keys held down and rebuild the library.
2 - run Option #4 to rebuild the database.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button and select the library you want to add in the selection window..
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the Library ➙ Rebuild Library menu option.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

My latest pano photo have missing landscape. Some of the photos are merged into one. I can provide the examples. What could cause this problem on a new 5C?

Thanks for the input. I was finally able to find some test conditions that duplicated the problem, and it is either that or some other out-of-spec diffraction distortion. So I sent it off for repair.

Missing thumbnails in Finder

Every now and again when I've had my MacBook Pro running for a period of time, the thumbnails for some of my files stop generating and is blank - just an empty white space. When I reboot/restart, the thumbnails come back. Does anyone know why? See attached screenshot, where the bottom two rows have blank thumbnails.

Yeah, apparently it's only an issue with external hard drives? Not a big deal to me. Just a slight pain at times, but clicking on the file name and hitting space still brings up a preview of the image, so that's enough for me until it gets fixed. Thanks!

In CS6 my created and then saved jpegs do not have the same icon as jpegs I receive from others. Whe

In CS6 my created and then saved jpegs do not have the same icon as jpegs I receive from others. When attached to email they don't actually attach but appear embedded in the email and vertically squished. Any ideas?

It could be as simple as having two different file extentions jpg vs jpeg. As for the emails, that may depend on how you are attaching them to the email.
In most email programs you can open a new document then choose file attach or file import. Former would be attachments or links and the latter would be embedded.
On windows systems you can also send images to the email app, in the explorer right clicking and sending would open a small app that will resize the image to reduce the file size. This app could in theory squish the image.

My new tab page displays only an empty grid. Missing thumbnails -and- sites. I -think- my settings are correct. Please advise.

What are the settings for clearing history when Firefox closes?
Make sure that you do not clear the Browsing Cache as that will remove the thumbnails that are stored in it.
