Pardon me for sounding like an idiot, but I'm about frothing at the mouth in frustration after spending over an hour on this, and searching here and at the Gallery site does NO good because it gets way too many search results, exactly zero of which have anything to do with answering my question. Namely: What the holy heck am I supposed to actually DO with the "gallery-plugins.xml" file? Keep in mind that this is also my first real attempt to use Gallery2 (been too happy with Gallery1 on my other sites for all these years) so if this is some incredibly well known process in G2, I don't know it because I haven't used G2 before.

I'll be over here in the corner whimpering and twitching, awaiting some kind soul's response --->

I am adding this gallery as part of upgrading vbulletin, and so this is all on a test server at the moment. Anyway, I have the thing installed and quasi-functional, but as soon as you click on an album, you are whisked out of the embedded environment. Why?
