ithmb - iPod and iPhone images

Recover ithmb images for iPod Photo File Juicer can convert ithmb files to TIFF. This is one of the few conversions File Juicer does, as ithmb is not a common format.
TIFF can preserve all the information from ithmb files, so this conversion is lossless.
The ithmb files are compressed using 16 bits per pixel in YUV format for television and they are therefore a bit smaller than the converted TIFF files.

Recover ithmb from the iPod Photo

Recover ithmb images for iPod Photo
  1. First - do not synchronize your empty iPhoto album with your iPod before you have everything recovered. See screen shot of iTunes below (where the synchronize is turned on).
  2. Then you need to make your iPod connected to your Mac as a hard disk.
    You do this by checking "enable disk use" for your iPod in iTunes.
  3. Then you can copy the .ithmb files, which are in the "/Photos/Thumbs" folder on your iPod, from your iPod to your hard disk.
  4. To convert the ithmb files to TIFF, drag and drop them into File Juicer.


The largest of the ithmb files on the iPod, "F1019_X.ithmb" on the iPod Photo (X is a number), can be converted to TIFF by File Juicer. They contain the same images as you can find in the iPod's Photo cache folder. They are small copies of your original images - 720 x 480 pixels.
Newer iPods may put the best images in F1023 or F1024. On the iPhone the best images (640x480) are in the F3008_1.ithmb, F3008_2.ithmb ... files.

The Tiny Versions

File Juicer can also extract the TIFF from the smaller ithmb files with the sizes: 176 x 220 pixels, 130 x 88 and 41 x 30 pixels. Usually you will only be interested in the images you can extract from the largest ithmb files.

iPhone and iPod Touch (difficult)

The thumbnails on the iPod Touch and the iPhone are also in ithmb format. They are a lot harder to copy to your Mac and you may consider contacting a professional recovery service for this task. This requires that you do a jailbreak to get to the files. QuickPwn is the simplest way to do it. Then you can enable OpenSSH with Cydia and connect to the iPod with the Terminal from your Mac and copy the ithmb files from the folder "/private/var/mobile/Media/Photos/Thumbs". F3008_1.ithmb has the best resolution. Then drop the F3008_1.ithmb onto File Jucier and you are done. The extracted TIFF files are the best representation of the images on the iPod, and the JPEG versions are carefully upscaled, to compensate a bit for the small size.

Using the iPod as a backup for your images

The iPod can automatically synchronize the full resolution images too, although it is not turned on by default. You may be reading this page because you have lost your Mac and your iPod is the last place you have your images. After you have recovered your ithmb files you can turn this checkbox on.

How to scale up converted ithmb images

If you lost the original images, and wish to scale up the rescued photos you can use bicubic resizing in PhotoShop Elements or for better quality Genuine Fractals.

iPhoto's files for smaller thumbnails

File Juicer can also extract icons from the iPhoto's and files. For more about extracting images from iPhoto.
