I'm sorry, I meant a transparent gif. ok, let me start again and explain what I want to do - I want to be able to have a slide fade in during a presentation and then to use that as a background over which I place other smaller images, fading in and out, then to continue to another full size slide. My idea is (was) to use a transparent slide, with the smaller images placed on it, so that the background image can still be seen. Thinking about it, it probably wouldn't work... So how do I do it?
