okay... I don't use categories on my forum, so I haven't tested this.

That Category is really a forum with no posts allowed. Its display on the FORUMHOME page is controlled by one of two templates (depending on your forum structure): forumhome_forumbit_level1_nopost, or forumhome_forumbit_level2_nopost

Within either of these templates (pick the appropriate one that your site uses), you should find the following line:

<td class="tcat" colspan="<if condition="$vboptions[showmoderatorcolumn]">6<else />5</if>">

you want to change it to put in the proper background image:

<td class="tcat" style="background-image:url([path to images]/catbg_$forum[forumid].jpg);background-repeat: no-repeat; 	background-position: center;" colspan="<if condition="$vboptions[showmoderatorcolumn]">6<else />5</if>">

Then name your images catbg_1.jpg or whatever (use the forum id of your specific categories). You will also need to set the path to the folder that you put them in on your server.

I hope this helps
