For example:
gPhotoshow would randomly grab Folder A, only show 20 images from Folder A, then switch to a different folder to show 20 more images.
The feature could be made to have the number of images shown per folder be customizable. I came up with this idea while playing with the scrapbook feature that has a similar concept. Do you think it's something that could be possible?
Welp, Just found out that feature was already in so you can ignore that, Great Job!
I do have a different idea though, for a different form of Photowall. Instead of having a Photowall that's constantly moving, how about a Photo Wall that acts similar to a normal image. It would generate an image from a batch of photos, hold on that for x amount of minutes, and then switch to a new page of photos?
So it would start and hold on this,

Before switching to this:

Would that be doable?
