What navigation at the bottom? The script I'm using just 
opens the window with the image in it - no next or 
previous buttons or browser chrome ... I probably 
should add a link to close it, though.

What I find annoying about it is that it covers up part of 
the page below, makes it a bit hard to select some 
images. But placing new windows always has that 
challenge.

Thanks, I'll have to check your scripts out. I'm no 
Javascript whiz, I just found one I could understand!
