Squeeze more out of a penny photo frame Digma pf 350?

Question

Electronic books

I bought a digital photo frame Digma pf 350 "for change" .
For basic functionality, in general, it is not needed - the display size is too small.
There was an idea to connect this miracle to a wifi router (dd-wrt flashed, usb-host available). I wanted to throw a generated picture with a weather forecast into the internal memory of the device by crown, for example. And hang this case in the hallway, just next to the router.
But here's the problem: the device, when connected via usb, asks whether to turn on mass storage or just charge. When choosing mass storage, the frame does not show a slide show and waits until it is disconnected from usb.
Are there any alternative firmware for such devices? Or how can I get around the problem?

Answer 1

I'm a plus!
If someone shares their experience on how to do such things on some other or this cheap photo frame, then I will gladly buy such a thing for experiments)

Answer 2

I think that inside the board there may be a system output for mini-usb, well, or you can just put a simple Linux there. Well, or do with it like a player from a magazine. :)
