Howdy, I'd really like an image slideshow program that does 2 additional things:

1. 1. Sub Folders
2. 2. Animated Gifs

Animated Gifs only play in the browser as far as I'm aware so they're going to be a huge hassle. Slide-showing sub-folders seems like it would be easier if we could find a CLI method of beginning a slideshow or just opening picture viewer in the fuller-screen mode. (unlike these commands)

Anybody know anything about accomplishing either of these things? I'm still a nub with linux, all I've accomplished so far is coming close to finding the length of an animated gif in seconds.
