well your banner does not look like the banner that was on your site when I installed classifieds because your forum was something different.

Thats the banner your using in the forum now and it seems to me you display your header using CSS right? I dont know I dont use Invisionboard and I think its real weird they cant assist you with their product.
Your somewhere calling this file in your css plus your hard coding another logo
