Jpeg Image file size for a Downloadable Product

I'm creating a site in BC for the client to sell digital download copies of their original photographs. The purpose of the product for the consumer would be to use the low res download as a screen save or for viewing in a gallery on a desktop, tablet or smartphone device. BC accommodates such products but I haven't a clue as to what size to upload the image files in the BC Product Details page.
Does anyone have any relevant information to share?

If the client intends on selling digital copies of the images, then I would make sure to make the previews small. Like 600 x 800 small. If it gets too big people aren't going to be inclined to pay for bigger.
I usually upload my photos in 1040 or 1280 on social media. But 1280 looks pretty good on most laptops. That'll change as screens get denser, but as of now I would think if I was trying to sell images and had previews at 1280 a lot of people would just take the 1280 and run.

Reducing image file size for web use without pixelation

Can anyone help me figure out how to best reduce images for fast web loading (in slideshows in Muse). I have done the save for web in PS and they are super pixelated now. The only versions that do not lose quality are the original size and they are huge files. Any help is appreciated.
Also can anyone tell me how big each image should be, what is considered a too big size (kb) for web images? Thanks Hillary

The settings I used were in the save for web panel and I saved the image as "medium" and the quality was 30, optimized was checked and it was scaled down to 16kb instead of 700kb. Is there a guideline as to how large in kb an image should be for good loading, it seems like with faster internet speeds we can go a bit larger for asset size. Is it OK to have an image as 65 kb if it is quite large (8 inched wide)?
I think I solved the problem. I just went in and saved the images as larger quality. I hope it does not slow things down too much. Any advice would help.

File Size for Rasterized vs. Smart Object Images

Hello,
I am scaling smaller images up to the full canvas size for a project (around 200% of original size). I have tried scaling images up as both a smart object, and also converting it to a rasterized layer, then scaling it up. I noticed that almost every time I leave the image a smart object and then scale the image up and save it for web, it is a smaller filesize than if I would convert it to a rasterized layer and then save it for web (sometimes up to 5% smaller). Does anyone know why this happens, or if it is changing the quality of the image by leaving it as a smart object?
Note: I am using very large images, with an original filesize of 1-3 MB.
Thanks for the help!

EDIT: Just to clarify, I am talking about the JPEG image file size being smaller, not the PSD file size
I do have maximum compatibiliy set for my PSD.
I am saving out all my images for this experiment out as a JPEG at 50% quality. I attached a screenshot of my save for web settings.
I also attached the rasterized image and the smart object image. I also attached the scaled down version of the image, which is what I am scaling up to create the rasterized and smart object images. Let me know if this is what you need to fully examine, and thank you for the help!
Here is the rasterized image:
Here is the smart object image:

File size with JPEG Image files

I recently had to re-load all of my photos from an external hard drive due to the fact that my hard drive crashed. When I did, I noticed that the files are JPEG Image files. As a result, the file size is considerably smaller than the original file and the quality is much less.
Any suggestions on how to restore the file to the original format and quality?

Connie:
Yes, it seems you backup the Data folder instead of the Originals folder. Unfortunately, there's nothing you can do at this time.
In the future, I suggest you copy the entire iPhoto Library folder to the external and then keep it updated with a backup application like Digital Backup, Snyk, etc. They compare B (the backup copy) with A (the working copy) and copy new or changed files from A to B to keep them identical. After the initial copy process, the subsequent backups are rather quick, about a minute or less.
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. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Where can I find the file sizes for each application before downloading?

Where can I find the file sizes for each application before downloading? I have limited download (525 MBs/day) because of Hughsnet and I need to know each applications total size before I download.

You can go to the trial page to get an estimated size. As the Creative Cloud products change over time though this may become less accurate.
If you are on a limited bandwidth account then you may want to consider purchasing a perpetual copy of Creative Suite 6 as opposed to subscribing to the Creative Cloud.

What is image dpi after "Reduce Image File Size"

Does anyone know the resulting image dpi after using the "Reduce Image File Size" command in pages? My mother is trying to prepare some things for pre-press, and can't send her document to the printing press, because the pages docs are friggin huge! I'm trying to give her the easiest option for resizing all of the many images in the document, but don't know if this is a viable option if the end product needs to be printed. I need the output to be at least 300dpi.

As fruhulda wrote, asking Pages to apply changes to the pictures isn't the good path.
In fact, it's a perfect way to get a fat file.
My practice is :
Prepare the document in Pages to define the wanted size of every embedded pictures.
Edit the picture files in a tool dedicated to this task so that the resulting files will be 300 dpis ones for the wanted sizes.
Then, replace the original pictures by the definitive ones.
In most cases, the file will be lighter than the original one and you will have the 300 dpis resolution (except if you apply shadows but it's an other story).

I need to save some pictures from iPhoto to a SDHC photo card for a digital frame and was wondering if there is a way to shrink or compress file size for each picture as I have already cropped the pictures? Thank you

Yes, you do this when you export the images from the Library.
File -> Export
in the Size section, you don't need images larger than the frame size, so you can specify that and in the Jpeg Quality you can select the amount of compression used.
This User Tip
https://discussions.apple.com/docs/DOC-4921
has details of the options in the Export dialogue.

Ideal file size for photos

If I am making photo albums in iWeb, what is the ideal file size for the photo file?
My camera now is 7 megapixel, so the original file sizes are about 3 MB, obviously that'll be very slow to load.
To what file size should I save it to make it load at a reasonable speed and still have a reasonable quality? 500 KB? 200 KB?
In case this is a factor, the typical album I make would have about 40 - 50 photos.
Also, what are the best ways to batch converts -- making a group of photos 500 KB instead of 3 MB? I know a few time-consuming ways (ie. individually resaving the files) or using a thumbnail-making program (have used a program called Thumbs Up).
Any other suggestions? Thanks.

If you are importing your photos directly from iPhoto to iWeb, they will be scaled down to a max dimension of 800x600. If you are using a photo template page or making a gallery page using the following method...
http://www.mac.com/web/en/Blog/013C4180-4787-4847-BAAB-319222AFC652.html
...iWeb will also make your thumbnails for you automatically.
For all your other freeform pages that you might make, it is always a good idea to size your photos down to their usage size. A good rule of thumb is to consider the width of your page, which by default is 700px. Then divide it out by how many photos across you expect to have roughly. So 3 photos across 700 pixels means that the photos should be scaled to roughly 233 pixels wide maximum. Just a rough approximation is fine.
The reason I recommend doing this is that if you drop in a 2500 pixel wide image into iWeb directly, and you only plan on using it as a 233 pixel wide image on the page... iWeb will do a fine job of scaling the photo down to size BUT it will also save the full resolution photo as part of your web page....not to use, but just for safe keeping. And if you ever discover the RSS feed on your website, you will see that iWeb makes all of these high resolution photos available for download, too! So beware if you value your original work! Don't feed them directly to iWeb.

Reduce file size for web use

Hello,
I created a website some months ago and I realize now the images are far too large and it takes a second for them to load. So I opened them in photoshop and changed the PPI to around 50, but the file size didn't shrink. I tried 10, and still nothing. I tried Save For Web and the file size got larger. Any ideas on how to keep the image quality (for web) but reduce the file size for easy page loading? Thank you.

Don't worry over the ppi value. That's arbitrary.
You can reduce the pixel count, by resampling. That will make an image smaller in a hurry. To do this, Image - Image Size, check the [ ] Resample Image checkbox, and change the pixel counts. I always set my Photoshop prefs so that I see the Image Size in pixels by default. If yours isn't reading in pixels by default, change the units so that it is.
However, you may need to have your images be a certain size, in pixels, and so resampling isn't an option. In that case, when you do File - Save As - JPEG (or use Save for Web & Devices), adjust the Quality value to get the image to the size you need.
Hope this helps!

How to reduce image file size in spreadsheet

I have created a spreadsheet that contains cells with small amounts of text, and images that I brought in from the Media Browser from iPhoto. This has caused the file size to become HUGE, on the order of 234 MB. Saving it as a pdf only reduces it to 220 MB.
I have tried the Format>Image>Reduce Image File Size, as well as File>Reduce File Size, but in both cases, those options are grayed out.
What am I doing wrong? All I really want is thumbnail versions of my image files.
I don't understand what the Reduce Image File Size command would be used for, if it doesn't work for this?

When you insert a picture in a cell, it's used as a background.
To do that, the app keep it in a size allowing it to accomodate the larger cell size permitted.
If you want to get small images matching the cell size which you use, you must reduce the picture by yourself before inserting it. For instance, cells are often 72 * 16 pixels ones so you may reduce your pictures so that thir width become 72 pixels.
Of course, if the user enlarge the cell, the picture will become highly pixelated.
Look at this example.
In B4 is the original : 202 x 177 pixels
In C3 is the reduced one : 72 x 63
in B2 is the reduced one in a 202 x 177 pixels cell. It's awfully pixelized
We must arbitrate between size and quality.

Maximum file size for export into MP4?

Hello,
I am not able to export 2 hour HD video into standard MP4 file. It seems that reaching 100% export algorithm gets into loop. I was waiting for hours and still had seen progress at exactly 100% with final file size on hard disk to be 0 bytes. I am using CS5 on MAC OS X. I had to split my timeline to 2 parts and to export them separately (which is embarrasing). Is there something like maximum file size for export? I guess that 2h video would have about 25-35GB.
Thank you
jiri

You are right.
So I am running AP Pro 5.0.4, Adobe Media Encoder 5.0.1.0 (64bit). Operating system Mac OS X ver 10.7.3. All applications are up to date.
MacBook Pro Intel i5 2.53GB, 8GB RAM, nVidia GT 330M 256 MB, 500GB HDD
Video is 1920x1080 (AVCHD) 25fps in a .MTS container (major part of timeline), 1280x720 30fps in .MOV container (2mins), Still images 4000x3000 in .JPG
No error message is generated during export - everything finishes without any problem...just file created has 0 byte size (as described above).
This is my largest video project (1h 54min) I dont have any other problem with other projects.
I dont run any other special software, at the moment of export all usual applications are closed so that MacBook "power" can go to Media Encoder. No codecs installed, using VLC Player or Quick Time.
Attached please find printscreen from Export settings (AP Pro). Writing this ppost I tried to export only the first 4mins from timeline where all kind of media is used...and it was OK.
As a next step I will try to export (same settings) 1h 30mins as I still believe problem comes with length of video exported.
Let me know your opinion

Session "Circular Kernel Context Logger" failed to start with the following error: 0xC0000035
As suggested above I assume this is a microsoft issue? It has been discussed here and other forums for quite some time. I never have seen a fix? I wish when we received errors of this nature microsoft would tell us what they were. How is this related to superfetch? What is superfetch? Why would superfetch have changed?
BY THE WAY.... Superfetch is on(started) is on automatic and logs on as local system. So this is not the cause of my issue. Also what is readyboot? Does the average computer really know what these programs/services or unique microsoft words/terms are?

Maximum Image file size flash can handle?

Does anyone knows the max image file size flash can load
using MovieClipLoader?
I tried 10.5 MB PNG file and Flash thinks it is loaded but,
the actual image never shows up.
Thanks,

Well it is good for that client. But it still won't work in
Flash. Sorry. You will need to slice the picture into different
chunks at 2880 x 2880 max and reassemble the tiles in Flash.
You may also run into an issue that things sometimes get lost
if there is more that 16,000 (or thereabouts) pixels difference in
their coordinates.

Is it possible to have same file size for different dpi?

I changed one.TIFF file (300dpi, 1024X1332) to .jpg files of four different dpi. But when I checked the four result jpg files, I found out that they are all in same file size and quality.( I also have checked the property of the files in the Windows.)
I think more DPI means more data and more file size. Am I wrong?
I use Photoshop CS 5.1(64bit, WINDOWS) - which is part of my Adobe Master Collection CS5.5.
TIFF(300dpi, 1024X1332) ->
1. JPG(72dpi, 1024X1332) : 306KB
2. JPG(108dpi, 1024X1332) : 306KB
3. JPG(144dpi, 1024X1332) : 306KB
4. JPG(600dpi, 1024X1332) : 306KB
I tested a few times more with different files. and same result comes out.(same file size for different dpi)
Thanks in advance.

Yes absolutely. Great observation. PPI does not control the number of pixels, just how big they are.
Now, if you change the PPI in the Image Size dialog with Resample checked.. then, that is a different story. In that case you will be changing the pixel dimension of an image (i.e.,changing the total number of pixels making up the image) while keeping its print size.
In your test files, you will notice all the print sizes are different, because all you were telling Photoshop to do was change the size of the pixels (if or when the image is ever printed), which is really just a bit of metadata of the file.
