Kind of an interesting situation. Currently I have a wallpaper set from my personal photos but those photos no longer exist. They were stored on my SD card, which was quite completely destroyed. However the wallpaper itself still remains, leading me to believe that the phone has created a duplicate of that file to store in the phone's memory. Where can I find this file? I would love to get this one photo back, and not just as a crappy screenshot.

Thank you!
