I've gotten some great leads from everyone. Thank you! I'm still working on it. I didn't make my requirements entirely clear. It's not a slide show. I'm looping through 500 images at 30 (or so) images per second, so I basically need an image per video frame. One of the high-end video editing programs should do it, or I may be able to sort out the transformations I need using my Linux tool set, thanks to Rikk's explanation of what's going on and Mark's article pointer. Thanks, everybody! I'll let you know how I did it once I've done it. Oh, and if anybody wants to do it *for* me in the next day or two (for pay, of course), let me know! I'm running out of time.
