I was a little confused Carole, thanks for your answer, I was just thinking it seems like a lot of money to spend for a gallery, and have all that wonderful IPS software hanging out there being unused, my personal opinion, get your community converted to IPS, you'll go through some growing pains for a very short while, but the reality is, IPS is waaaay more intuitive for members to use, upload images, post topics, etc etc, I know as an administrator you have your own reasons for not doing just that, but it sure seems like it would confuse members to be using two different software, not that it's not done, but I see headaches in the future for you if you are going to start an IPS gallery for your bbPress members to add images too, then when you do go to convert your bbPress to IPS, it's going to be weird, I cannot pinpoint or give you examples of the weirdness and headaches you may experience, it's just my gut feeling that it may be a headache.
I do believe IPS has a wonderful conversion tool for transferring all your topics, posts, members and much more over to IPS. I came from a proprietary software named NING, they don't offer that conversion tool anymore, because it was a headache for IPS gurus, but even as hard as that conversion was, it was very successful.
Just my opinions, which are worth about a penny anywhere! 😄
