Cloud storage app with slideshow?

I'm looking for a Cloud storage app with a built-in slideshow viewer for photos.
But I also want to be able to organize and browse by folder.
Dropbox has great folder organization but it has no slideshow.
Pogoplug has a slideshow but it insists on ignoring my folders and lumping all photos across all folders simply by date.
Bitcasa is a little in-between except it seems to display the photos within the folder in a seemingly random order.

Any other recommendations?
