Yes on the bridge and Gallery Pro question.
In the earlier years I played around with lots of gallery programs including CPG, SMF Gallery Pro and Gallery2. After trying all those options I settled on G-Pro because the staff at cpg at that time were so difficult to deal with... they used the karma system like a 10# sledge hammer.

So, after my delightful [/sarcasm] year off, when I started too rebuild the site I tried CPG again because I've always liked it and there were rumors that they now have some staff members who are just wonderful.

But, eventually I returned to G-Pro because I like it a little better than CPG
For starters I'm going to take a closer look at the slideshow that you built for TP to see if it will work here... may also do a bit of a Google search to see what I can find.
