what is a good lcd photo frame that is battery powered. i want to put it up without a wire hanging out the back. i will have access to change the batteries in the future. how quick do they go through batteries? what sort of batteries do i need to get

My brother got one from Amazon, it's an 8" display by Linx. That is battery powered. I think most have a battery.

are the newer ones available with batteries? I'm looking at 10+ inch frames. I don't want a wire running to it if I can get away with it.
