Jan, thanks so much for sharing the links. The OWH one did not work for me, but I have to say the video did exactly what I was thinking of doing for a future example and now I don't need to do the extra work! I like how she showed the one that was nice but not quite as nice as the other, and why. Great idea to make a viewer.
I had forgotten that I meant to mention that I am not an expert in design, in no way, shape or form. But I am interested in it and I thought we could explore together, for the first time or umpteenth.
