Click on the "Save Snapshot" button above the preview screen and then pick either JPG or PNG as your format.
If you are talking an entire series of still frames, either use a script to do this task OR frameserve to an external program that will save the individual images.
Sure, I knew that. I was just testing to make sure you guys (gals) knew that. Thanks, "Best-Full and click the floppy" - got it. I guess I'll need to start learning about the scripts, as jetdv said, if I wish to export an event as a series of still images. Perhaps V6 will have this feature. But this works.
