I'm pretty sure this week @Mike will reach 10,000 likes! He deserves it, he's awesome!
Congrats for the hard work you're doing Mike - you rock man, seriously!
PS. Mike, are you going to implement basic album functionality (with likes, comments, and so) in XenForo 1.3?
Features will be announced in either the HYS forum or the announcement forums. There is a suggestion for what you want, I suggest you follow those forums/suggestion for news about albums.
I'm sure now that the resource manager is well out there there will be further development around making it more flexible for other uses and hopefully for multiple instances. Somewhere in all that I believe gallery functionality could be configured.
