How to zoom on the images after each fade in animation?

Please help! I need to fade in three photos to a frame, but would like to zoom in after each fade in to the just revealed photo. Currently the pictures all fade in one after the other, and then it zooms in to each one in sequence.

Thanks Vanda, it took quite a lot of experimenting but I think I’ve got there in the end. What a crazy way to have to do this though, it could be so much simpler with a few more options added into the user interface. Thanks for your help.
