I'm still a noob with joomla and bridging but, after reading and following the instructions on Mehdi's site, I have the gallery bridged and working just fine.

I still have to experiment a little with the .css stuff so that I can get a fairly seamless integration with the template I use for my website but this was a painless install once I figured out what I was reading wrong.

Again, follow the instructions on Mehdi's site and it will bridge perfectly.
