My Galaxy S5 has a pic that shows in my wallpaper menu but not in the picture gallery. Likely I deleted it from the gallery some time ago. Anyway, I'd like to save the pic as part of a phone backup. There is no option to copy or save it from the wallpaper menu.. I copied the pic from the web someplace but before breakfast so the location is erased from my memory bank. Is there any kind of wizardry that can recover it from the wallpaper menu? Otherwise I'll re-dredge the web for it.
This is a very desirable pic: the Pittsburgh Steelers' logo centered on a black and gray cheese grater background. 
OK emergency over. It actually took less time to refind the pic on the web than to type the above post. Maybe some moderator could delete this thread.
