you can add an image in place of the custom title now. just edit the user's profile and put in:
, instead of 'Whatever Custom title'
the image will show up. i believe that's what is done over at ubbcentral for the ubbtester, ubbdeveloper 'custom titles'
edit: whoops, i see you already know that.. my bad
ps: what i did (to make it easier -- sans a drop down) is to add 3 sql commands to the list of saved queries in cpanel.. they essentially do the equivalent of your drop-down.
update ubbt_USER_PROFILE set USER_CUSTOM_TITLE='
' where USER_ID=xxx
this is done for 3 different images or 'ratings' i want to use.. then i just fill in the 'xxx' part and execute the query..
it's maybe a little easier.. but definitely not as easy as a pull-down..
