* Will the gallery be of a similar style to the forum once I've added it? I've read a lot about photopost not having vbulletin template support and was wondering if that would be a factor. I've not got much customised in my vbulletin templates but would prefer not to have to mess around with that too much.
Photopost is a separate application and we integrate with
vb in the manner of user integration and header footer stylesheet. Here are some examples

* I want the gallery to be available to one specific usergroup that pays a subscription and invisible to everyone else. Is this possible? If so how easy is it to accomplish?
Yes you may set permissions based on usergroups within our software
* I have vBadvanced installed as a content management system for the front page of the website. Will I be able to add links to the gallery on here? Again viewable only by the subscription usergroup?
If you use the proper vbulletin coding to show a link based on usergroup in
vb surely you can do so.
