No multiple photos per post is not a feature in our gallery. I did not even know ubb had a gallery but then again its not something they sell I see its part of the actual forum code. We have two products that allow multiple images per post and thats reviewpost and classifieds. The very nature of a gallery is to have all comments about one photo the user posted. In fact I beleive ubb is unique in there thoughts about multiple images per photo posting. You might be able to modify reviewpost to your needs. I do see why your looking around for another gallery software though there features in that little gallery you use are very sparse.
