I would like to use my Raspberry Pi 3 to deliver photos from a USB (or HDD via network or wifi) to a video screen (not a TV), sort of a changing picture. There are commercial models available but I have a surplus large screen with DVI, RJ45 and HDMI inputs. I plan to mount the screen in a picture frame. I would appreciate any thoughts on software etc
There was a rather nice network connected picture frame project by fvan here on Element 14 not so long ago
Raspberry Pi Connected Picture Frame
Also this video player project may be of some interest - although not a picture frame, it demonstrates a turnkey type display solution
