Here’s a great, FREE solution for simple image rotation in joomla.   You can’t assign URL’s to different images but you can assign one URL link for all images.   This is not a solution for banners, but is a nice eye-candy advertisement.

You can change transition time and force automatic resizing on width and height.

It worked great for a “Top Sellers” application where all clicks went to the same e-store.
