I'll see what I can put together for a "how to" instruction block. You will have to use phpmyadmin or just enter the sql commands from the admin section of UBBT to create and fill the field needed. I called it Bo_Topicon. The graphic sizes are not stored (they should be though, at some point) so that's hard coded in the ubbthreads.php script. They must all be the same size or just don't specify one in the image tag.
With some luck I'll put the instructions in a text file tomorrow or maybe friday night. []/forum/images/icons/smile.gif[/]
