Widget to allow swf file in sidebar

I’m looking for a widget that will allow me to insert a simple flash file / slideshow into a sidebar, and that plays automatically / autostart.

I can create the slideshow in flash or – am happy to just upload jpgs to a folder and create a simple slideshow – but I don’t want any user interactivity. I’ve tried a few that just don’t quite do what I am hoping for. Nextgen, which is nice – but I haven’t figured out if there’s an autostart feature. Any ideas? Just a simple auto start slideshow for a sidebar.
Simplest of all, is there any way to get the wysiwig that’s normally on a page and allows swf uploads – can any widget enable that capability into your sidebar?
Many thanks in advance!
