What version of Ps are you running?
That will help others point you to the correct proceedure.
Good luck, and please let us know just a bit more.
I'm using PS6.
I wasn't sure how to animate so I went to PS Online Help and searched for animate. I got this link:
I followed the directions (had all my photos in one file, did File,Open. Then clicked on the first image in my sequence, checked the Image Sequence option, and clicked Open. I haven't edited any video in PS before but the screen that opened looked like one that would be used for video. However, only the photo that I had selected was open. I assumed, from the help file above, that all of the photos would open. I also don't know what I should do to make it into a video.
