I had this image slider for Joomla 1.5. It was definitely the best (free) slider that I have come across. When I upgraded to Joomla 1.6, I was concerned that this module would no longer work properly. The developer, however, was quick to release a 1.6 native version. There aren't many 1.6 compatible extensions out yet, so this says a lot about the developer. Top notch extension. Top notch service!
