Thanks! Quick note, in the v 0.2 zip file photopost.inc.php, localhost is misspelled on line 12.
Now, for me (running UBBT 7.1b5) it opens a window that says "My PhotoPost Pictures", but there are no pics displayed, just the heading and then the two buttons at the bottom. When I go directly to my photopost install, I am logged in and have pix in my gallery. Any thoughts on why it's not finding any pix?
