Animated/Slide Show themes?|PS3 Themes|Forum|PS3 Themes

I've seen the dynamic theme editor, but it doesn't say wheter or not I could make a slideshow theme/background with it. I've been googling for hours now and can't find anything.

Can that editor be used to make slideshow backgrounds, if so, is there a guide to do it? I'm aware of the regular themes that change backgrounds when ever you re-apply the theme, play and a game and quit, etc. I'd just really like a theme that changes every 10 or 15 seconds with some of my favorite wallpapers.
