image location when installed in sub-folder…

I searched for this, but couldn’t find it. My wife says I can’t find anything unless it jumps from the shelf into my hands.

Anyway, I installed WP in a place other than my root, so it’s here:
http://www.mydomainname.com/myblog

The problem is that when I upload an image and then try to insert it with WP, it looks here:
http://www.mydomainname.com/wp-content/2006/06/image.jpg for my image.

Naturally, my image is here instead:
http://www.mydomainname.com/myblog/wp-content/2006/06/image.jpg.

Is there a way I can make the editor look in the “myblog” folder?

Thanks!
