One other thing while I'm still awake ... and maybe a techy point for Anne to consider ...
When I click Mark's side view of the jellyfish no full size window is given. Is this perhaps because it exceeds a system pixel size? Side of blue jellyfish ... 1048 x 1213 pixels.
The photo of the top of the blue jellyfish ... 1106 x 1119 pixles, does produce a separate full sized window.
My screen is 17", with 1280 x 1024 resolution, so perhaps it's a case of the height of the Side View photo being too much for my screen. We know that some folk will have problems anyway trying to view any large dimension image, but usually my display will work ok.
