[MPDev]

http://www.photopostdev.com is a good example site of integrated PhotoPost/ReviewPost/Classifieds - we have 5 fulltime support staff and did have some growing pains issues about a year ago when PP really took off, but those have been resolved. (A good example of going the extra mile is a thread posted here from some people having trouble who all got the help they needed to have their sites running smoothly in no time.)

PhotoPost was the first gallery to focus on integration with forums and to use a forum layout. Many of the features you see popping up on gallery products today were innovated by PhotoPost. We've also kept an aggressive development schedule for several years and the current 4.8 version which integrates with vB3 styles is no exception (look for updates to all three products to use the integrated styles shortly).

If you are looking for a free product - there are several decent options and trying doesn't cost you anything but time. But for the price, PhotoPost offers alot of advantages that you don't get with free products.
