Hi Chris, most Digital Photo Frames are mains powered, using a mains adapter, and the battery is just for back-up, so that they keep the time and date settings. If I find one that will work on batteries alone, I'll post the details here.
The only frames I know of that work on batteries alone, are the small keyring types, and they're too small.
I guess the only other solution would be to have a power socket that is out of reach, and, more importantly, out of sight.
Some frames can be wall mounted, so if the cable can be hidden in a plastic conduit, so that it looks as if it has been hard wired, a bit like a ceiling or wall light, that may also be a solution, again, so long as the power socket is out of reach and out of sight.
