I need a battery operated digital Photo Frame.?

My 80yr old aunt lives in England and does not have a computer. My 86yr old dad lives in America and has scanned all the old pictures into his PC and uses them as a screen saver. She loves looking at them. she is coming to visit in september and i want to get her a Photo Frame and load it with the pictures. My problem is the AC and want to make it battery operated. Can anyone help?

There were some battery operated frames at first but the batteries only lasted an hour or so.

In theory, you could attache a BIG battery to the frame that matches the output of the transformer that comes with the frames.
