How can I restore an old background on a mac?
Today I created a collage on CollageIt Pro and made it my backround. Then when i restarted my computer, it was gone! How can i restore, or find the wallpaper i had before? (i do have a time machine back up but i could not find the picture). And it seems to be that the collage is nowhere to be found.
