I'd happily give it five stars if it better supported handhelds. It seems to be Flash based and iDevices of coarse hate Flash. It kind of works on handhelds but the settings don't translate and you have to tap to switch to full screen before it shines on handhelds iDevices. On desktops it works great and gets a solid five stars from me! Looks slick and professional and the full screen mode works well. I'd like it to switch to full screen when you click on an image which is my sole complaint on a desktop. I had to include instructions to click on the FS to go to full screen which could be avoided with that one addition. Still this is the best slideshow software I've found. Make some tweaks and I'll happily up it to five stars.
