I've been beta-testing Picnik's Show and gave them a lot of feedback.
"Why do we need another Flash slideshow widget?" In true Picnik fashion, they have near-unparalleled ease-of-use and some smile-inducing goodies. What you see above is Documentary mode, which couldn't be named "Ken Burns" for legal reasons I suspect. I set my slide interval to 1 second so it moves along at a zippity pace. Lemme know if it causes bandwidth jam. Apparently, I take many more pictures of my Second Life than my first one.
Importing 100 pics (the max) from a Flickr set was easy to do. I wish like PictoBrowser (as described here), I could create a Show that keeps refreshing based on an auto-updated set. Such a feature is wonderful but overlooked, and would allow me to embed a Show always showing my latest SL adventures, based on my Second Life Exploring Flickr set.
