I have finally gotten VB Image Hosting to work at my site. Most of my problem was being a complete newbie, and not getting the files in the right places in my home directory. In particular I hadn't put a .xml file in the .xml folder.
The Instructions in the install guide were a little hard to follow. But then, I think they were written to a more experienced audiance. Waiel was very helpful through e-mail, and patiently got me going right.
My members are very happy with this! Good work, Waiel!
