Does anyone know how to make animated icons? Or where I can find one of Castle, of the scene where he says: "I don't want the bodies, just the pics". And then he makes that cute face.

If your goal is just to make an interlaced icon, I recommend link. It's fantastic for stringing multiple icons together, and plus there's no download involved. I used the same program to make link and link.

As for caps for Castle (aha, alliteration!), I'm not sure where you might be able to find that. I'll get back to you.

Well maybe try to see if google has what your looking for.
