In response to your question, the best way would be by creating a PHP module (because in order to get the permissions from both vBulletin and vBGallery you would want to query from the vB tables) similar to the CMPS module that Zachariah has released.
Thanks, KW, though I'm still stuck on start since I don't have a CMPS front page and I'm not experienced enough to do this without instructions. Would you know of a link to a hack/module/whatever it may be called?
When I get back home tonight I'll poke around the various forums to see if anybody has released something similar before I re-invent the wheel. PhotoPost PHP Pro includes a PHP script just for that purpose but it is not a feature of PhotoPost vBGallery so if somebody hasn't released a hack already to do it then we'll have to start from scratch.
