Maybe I am missing something, but what happens with the picture url in the user profile? When I look at user list, it shows their avatar, not the picture from the picture URL.

I am just testing out the features, so my posts aren't imported or anything but site is at http://www.tropictravelonline.com/ubbthreads/ubbthreads.php

AFAIK there is no picture area in Threads7; its a used feature at a lot of sites, so its a shame it's not being used anymore.
