Easy Backstretch works great! I know it's early days, so I have two suggestions for future versions:
1) Limit instance to a single page. I can replicate this with page classes in my theme, but many themes don't have that feature (and many users aren't savvy with CSS). It would be useful to allow users to select the page -- or, at a minimum, include a check box to limit the instance to the home page.
2) Re-Order images. I'm going to poke around the code and see if there's a way to finagle this, but if there was a way to re-order images once they're uploaded that would be VERY helpful. Sometimes the best order doesn't reveal itself until one sees the slider in action.
Kudos to Marco and Gabriele!
