There are dozens.
Here's an example I set up for someone last month: http://www.ebonyaura.com/slideshow.zip
It's xml driven so all you have to do to add/change the images is edit the slideshow.xml file. The "dir" attribute needs to be your images folder (relative to your html page) and you can also set the slide length and fade time (both in seconds).
The default location of your xml is "xml/slideshow.xml" but if you need to change that for some reason, just change "slide_show_220x340.swf" to "slide_show_220x340.swf?xml_url=newfolder/newfilename.xml" in your embed and param html elements.
Changing the width height is also just as easy as changing your document size inside the .fla.
You can also edit the loading animation inside the .fla.
