[Web4lib] need some free design advice

[Sharon Foster]

Thank you, Graeme! I did think about having one style sheet for each
image and randomly selecting one when the page loads, but this is much
cooler. And, you may have noticed, the page has issues in IE even now.
I'm pretty sure that wasn't caused by anything I touched, but I didn't
save a copy of the old page so I could compare.
