On a limited basis, It can be done.
Using XP Media Centre, including Media Player, I have My Photos and My Videos as file folders. When I bring up Beoplayer, and click to activate My Photos, I can see and hear the video clips I have. I'm ML linked to a BS 3200 and BL 4000 system.
I use the same Sony T-70 to shoot both, downloading the shots into the PC. Using a 4G Memory stick, some of the clips can be a few minutes long. The differentation of the photos to the video is seen with 35 mm film corner simulation around the video clips. If I select slideshow, the clips play one after another as they do with Media Centre.
Perhaps this is not an intended feature as I've been told, but tt has worked for a number of years.
