Just a thought ...... but you can get both free and paid for gallery add-ons for vBulletin.
When we moved to eUKhost from cheap hosting ( vBulletin based) and noticed a vast improvement in page loading speeds and reliability.
Support did our transfer for us and it was flawless.
Our recent problems that we have had are seemingly because we are basically getting to ''big for our boots'' and are having to upgrade...but once again Support have helped all the way.
