Replace Image Banner With Adsense Code

Hello everybody!

After going through and solving my last 50 problems with google and my own knowledge….I’ve hit a wall

In my theme, there is the option to make your own static ad with a preset image size and a URL…which is cool…but not very interactive and by no means dynamic. I’ve already got everything set up in the style.css of the theme…now I just want to implement my Adsense code into the header.php file…but I’m not exactly sure how to even go about doing it. I’m pretty sure it’s the only file I need to edit…I’ve gone through everything else.

I don’t want to be one of those people who posts a whole file of code, so just wondering if anyone would like to help me through this one? 😀

Also…exactly how many/which kinds of problems can I post without becoming a problem child haha? I kinda sorta also have the problem of centering widget images and making the sidebar background all one color X) but that’s a story for another day…
