Apple iPod photo thumbnail
File type: Graphics file
The ithumb file extension identifies a thumbnail file used by the Apple iPod.
An ithumb file contains thumbnail images for pictures and digital photos stored on an iPod. It is a proprietary supporting file rather than a normal, user-editable image file.

The ithumb file extension is associated with the Apple iPod, a portable multimedia playback device developed by Apple.
An ithumb file stores reduced-size previews of pictures and digital photos on the iPod. The device uses these thumbnails to display photo lists and previews without loading the full-size images.
These files are created and managed by the iPod's photo-management software and normally form part of the device's internal photo data. They are not intended to be edited manually.
An ithumb file is not normally opened directly. Standard image viewers generally cannot interpret this proprietary iPod thumbnail format.
To view the associated photos, connect the iPod to a computer and use software that can read and transfer photos from an iPod photo library. Such software may display the thumbnails or export the corresponding photos instead of opening the file itself.
An ithumb file is a device thumbnail rather than the original photograph, so it is not normally converted directly to a standard image format.
When possible, export the original photos from the iPod or restore them from the computer's photo library.
