Very interesting, I had no idea on all the wildcard stuff. I tried the
above lines and still no luck, unfortunately, on getting the server to
allow direct linking to pics from the forums. This time around though,
rather than just shoot me to the front page it gave me a "Server Error"
page(just that generic one you get). I think we may be getting closer.
I'll play around with it a bit more, see if I can catch any luck.
Again, I appreciate your help and especially the info! :)

Thanks,
