This will convert the animated GIF of your choice to the Flash format SWF.

This SWF file can be used in a webpage just like any other SWF file. You can press the "View HTML" for the source code to put into your HTML page.

The SWF generated by this is not usable with Firestarter. You can't convert an animated GIF into SWF and then use it in Firestarter to add other effects.
