I have used this program for a number of years. The developer has listened to their users and continues to develop and add new features on a timely basis. Their are many programs out there that make slide shows but this one stands out. It is very easy to add 1 to multiple key frames and output is seamless and smooth. If you really want to step up your slide show presentations, I would highly recommend taking a good look at Photo to Movie. The support has been excellent with timely responses to queries and it has proven to be well worth the price. I am a slide show junkie and get raves for the output from this program. I hope these comments prove helpful.
