I'm an idiot! I thought that Desktop Manager 6 backed up my media files and it didn't, and I did a Security Wipe to try to fix another problem, and now alllll my photos are gone! I am about in tears and am desperately hoping that someone has a miracle cure that can get them back? Plleeease someone help me! :(

Are then not stored on the SD Card? If not, they are truly gone. There is no "undo" function.

If you ever backed up your device then restore only the Content database, this has device photos.
