When doing a bit of Google searching for content on our blog, I noticed to my shock and horror that individual images from the Media Library are somehow generating their own URLs that Google is somehow finding and indexing!

For example this page:  

<http://blog.stackoverflow.com/2008/08/special-development-team-podcast/>

Contains this image:  

<http://blog.stackoverflow.com/wp-content/uploads/bio-jarrod-dixon.jpg>

Which is fine, but somehow this image is also exposed as its own URL and "post":  

<http://blog.stackoverflow.com/2008/08/special-development-team-podcast/bio-jarrod-dixon/>

This is *extremely* unwanted! 

I checked the Media settings in WordPress and browsed around the Media Library but I can't figure out a way to disable this behavior. Any ideas?
