Nah, you should use the vBulletin integration. vBportal is totally different. I do still have my old PhotoPost config file though... If you think that would help I can email it to you.
And actually the photo gallery I'm working on will just be a small part of a much larger script. It will be
somewhat similar to vBportal, but MUCH better, many more options and scripts, and much less server intensive. Plus it will probably be priced about the same as or less than PhotoPost.
