Roger, Thanks for that, I am indeed using a black screen so that must be where it's going wrong. I'd have thought that I'd be able to select a shadow colour (i.e. grey) and it would turn out a treat. Obviously not from what you suggest. I have my pictures at 75% coverage, so it's clearly your first point where I'm going wrong. Never mind, my slide shows look a treat anyway and I'm dead chuffed with them pretty much the way they're turning out. Thanks for your suggestions. Regards Dennis (London, England)
