I use the subBlack theme, so im not sure if I have to edit in this or not...but the logo file is very small...about 1 inch high, 3 wide and is in the top left corner. I want to make it so I can put one that take's up most of the top part of the screen. I was just curious how and what would I edit to do this? I am totally php illiterate. So I really do not know where to begin with this, would anyone have a clue? Im looking to make the logo about maybe 2.5 inches high, and 10 inches wide maybe.

The one you're looking at is at this location /themes/fiblack3d/forums/images/logo.jpg and is used as linkback to your homepage no matter where you are on your site, ala the nukemods logo here. The one you're probably going to want to edit is /themes/fiblack3d/style/images/cellpic_bkg.jpg .
