I've photopost too. It's installed on
http://www.myhotboard.com/hotphoto/hotpix But our 'Showcase' (which we want to integrate with UBB-T user logins) are way too big - to the range of 2Gig of Images averaging 40KB each. Also we figured out that bulk uploading in Photopost does not work well. Plus, we want to keep the already popular format for these pics as well. We have kept Photopost separate for member uploads only.
Thanks.
