i have some pics becoming totally gray in download folder. after i restart the tablet, those pics become normal again!

what could cause this problem? it has happened twice already. before that, i thought that i lost those pics forever, i just delete them.

I wonder if Android does links to these files. Did you move/copy these files from one folder to another folder? Or open/import them with an application?
