For animated gifs use UnFREEz2.1 from http://www.whitsoftdev.com/unfreez/
Its only 20KB zipped and works well.
I don't think it does fades, it's just for rotating images at any interval you set.
Can anyone tell me how to rotate pictures on a website? Fade-in and out effects too. I have Fireworks, but not photoshop, so I don't think the fade-in and out effects are possible in Fireworks. I'm interested in different ways this can be done and with different software. Please reply with any knowledge or idea.
