I have a LG Voyager and I decided to put different wallpapers on since I've had the standard one that comes with the cell for a long time now. I have an SD card so I decided I'd get some pictures and put them on there. It worked, sort of. Two pictures (both I got off the internet, both of which were pictures of Fallout 3) worked. However, 2 pictures that I made myself in Photoshop (after I put the Fallout 3 pictures on) did not. I saved them with the same file type as the Fallout pictures but it didn't change anything. Does anybody know what file types work best on cellphones or what I need to do to make these work?
