ITHMB files are used by iPod devices that can display photographic images.

The iPod photo application can display up to 25 photo thumbnails at a time. When the thumbnail is clicked on, the full version of the image can be viewed. The ITHMB files contain all of the thumbnails in a single file, with each file containing 25 different thumbnail images.
