DiskDigger scans your device's memory card or internal memory for deleted photos and images

DiskDigger

Whether you accidentally deleted a photo, or even reformatted your memory card, DiskDigger can find your lost pictures and lets you restore them, or send them to an email account
.
For complete instructions, please see http://diskdigger.org/android

Again, this app is for rooted devices only! This is also a work-in-progress app (and not nearly as powerful as the original DiskDigger for Windows), so all constructive feedback and requests for features are welcome!
