Jhmac,
Wow, I was just going over posts where I wasn't the last to respond and just realized I never got back to this one. Very sorry for the delay. I do see you subscribed, so if you do run into issues, just let us know.
As for your question here about the Gallery extension, I'm actually pretty familiar with it as I run another site with Gallery. However, that site isn't bridged to Joomla, so I don't know as much about that aspect. Basically, (for all bridged software to Joomla), if the content is 'pulled' from the other extension and displayed within your Joomla template, generally, JFBConnect should work just like normal, easy-tags and all. The main thing is that our 'tags' (and most other features) work using our JFBConnect System plugin. If that is executed on the page, it parses out the tags and replaces them with the correct info for Facebook to use. So, if the bridge is executing those plugins on the output, you should be good to go.
As mentioned, if you run into issues, just let us know. Once again, I apologize for the delay, and hope all is well with your site(s)!
Thanks,
Alex
