Hi Julia If you are into Photoshop it is dead easy - your show becomes a number of layers in a Photoshop file with the bottom layer as your background. You keep adding your new images layer by layer and each layer can be as different as you want it to be. You switch layers off and on to build up the sequence you want to present. If you are not into Photoshop, then I'm stuck too ...! Regards Alastair (akphoto)
