preview

I'm working on a program that generates an image. I can keep the image open in Preview and when the image changes, Preview refreshes it, but only when I alt-tab (sorry, command-tab) to it. I'd like to keep the image in view and have it auto-refresh without touching it. Is that possible?

(One ridiculous way I've found to do this is with a script that converts the image to a PDF file which I can keep open in Skim.app (a PDF reader) which has that ability.)
