I've got 4 different photo programs on my computer including Photoshop Elements, but I can't find anything that tells me the dpi on my digital photos. On occasion, I've needed to send a digital photo to someone at, say, 300 dpi -- and the only option I could find was to make a print, then scan it at that resolution and resave on the computer. Surely there's a way -- what am I missing? Help!
