a slde show to run on Photobridge that would randomly go through my organized folders in My Pictures on my PC.
I do something similar with XP SP2 and Windows Media Connect (WMC V2), i.e. UPnP. This works well for pictures and music. I still use an SMB share for video (for MPlay).
This thread discusses what I had to do to get WMC2 running...
WMC allows you to see your pictures organized by
all your pictures,
If you select the all pictures folder and "play" a picture, it will go through all your pictures regardless of the folders they're stored in. I think they're sorted by name by default, and I'm not sure you have many options for the play back order (right now). But I haven't looked yet. Also, I expect many features are in the works.
