Where WordPress stores the URL for the Image Header

Hello,

I am having a real headache here. I changed the location of my blog (newlocation.com) and many images disappeared.

The problem is that the blog looks for the images in the old location (oldlocation.com).

I do not want to upload all the images anymore, therefore I want to tell WordPress that it has to look in the new location. From general settings in the admin page I can choose the WordPress address and Site address URLs but apprently they do not apply for the uploaded images (I see from the source of the page that the img src is still pointing to the old location).

The only way to make the blog understand that the location changed is to modify it from the database. The problem is that I cannot find it.

anybody knows it? Thanks
