Banners not showing correct size.

[fiddler]

I have just installed the module Banners 2.3.1 on CMSMS 1.6.5 on the website http://trophydeerhunters.com
The banner size is actually 720 w x 90 h, but is showing as 450 w x 68 h.  I changed the size in the banners list template to 720 x 90 - is there somewhere else that needs to have the size changed to get the banner to show at the correct size?
Thanks for your time.

version 2.3.2 doesn't solve this problem.
