Hmm, well I've diverged from the original template so I edited layout.html thusly:
Created a new stattopx, statmidx, & statbotx classes with new bitmaps which are expanded to 400px wide.
Modified the table entry surrounding <!--System:PopularThreads--> to use the new classes and added cellspacing=10 align=left to make it sit right.

Thank you for the quick response.

That works too. Glad you got something worked out.
