Header help

Hello,

What I am looking to do is edit my header image so the title and slogan aren’t text. I was wondering if there is anyway I can do this or is WordPress going to automatically add the text?

Also, I am going to paste the code for my header. If you look at my blog http;//www.corporateblack.com. I want the title, and slogan to show up like a normal website. Instead of it just displaying CorporateBlack. Maybe someone can tell me which code to delete or edit to make this happen.

Thank you in advance! Regards,
Matt
