Hi Lin, Thanks for the reply and suggestion. I must admit I have just copped out and re-imported all the images into a new file and they are appear as they should. All I was trying to do was a simple fade transition from one image to another and the images are on separate pages. Each image file has a different name so have no relation to each other. I had done this before and it has been no problem but for some reason I still cannot fathom it did not behave itself this time. The problem has been worked around rather than solved and that is good enough for me as I am under a bit of time pressure. A big thank you for being so helpful and I am sure I will asking more questions in future. David
