Attached images, removing the link?

Hi,

First off just wanted to say that I’m loving wordpress, it’s turned my site into something really special so thanks.

I’ve got a news page which frequently posts images attached to the stories. When wordpress inserts the image it always links to the original sized photo (even if it is the fullsize). Is there a way to set it so that the images don’t link?

Any help would be greatly appreciated. Many thanks.
