They old Gallery software was a serious pain in the neck for me to maintain/update/make new "categories" (eg, Single in January), etc. Trying to get it working with the new forum software was the final straw. Once I saw that Xenforo had a Gallery option that could import all our Gallery photos, comments, galleries, etc, I jumped on it. To me it looks a lot nicer than the old one, plus it scales for mobile and restores our ability to post images directly from our galleries into posts using the button. Let me know what you think!
