I had a bad experience with another slideshow plugin not working in IE and was desperate for a solution. I had BT Slideshow Pro up and running in less than 5 minutes. Everything is on the module page and it is quick, easy, and seamless. Works beautifully in Internet Explorer, Firefox and Chrome (that's all I checked). Gorgeous slideshows with awesome effects and for $25 quite a bargain! Kudos to the developer for an excellent product!
