Hi,
I have a gallery that I'm trying to set up for a client (it's got some
pornographic pics on it - so if your sensibilities are offended by that, you
might want to skip it :) ).
The page is at
http://www.eroticaboxing.com/08gallery/index.php?gallery=gallery1
The php code I'm using sets everything up nicely with thumbnails, etc.,
but the thumbnails themselves don't link to a larger pic - instead, there's
a text link below each thumbnail that says "enlarge". I've pasted the code
below, and I was hoping one of y'all could tell me how to change it so the
the thumbnail was the link?
Thanks...!
