hide or shorten urls to (wp-content/uploads) folder?

I am trying ti hide or shorten the link to files or picture uploaded to the wp-content/uploads folder.
By default in WordPress if you upload and image, pdf, etc and insert it into a post or page it will have a link like this:
“http://www.mysite.com/wp-content/uploads/2009/08/picture.jpg”
I want to hide the reference to all WP folders on my site. I am trying to find a way that the URL will display like this instead.
“http://www.mysite.com/uploads/2009/08/picture.jpg”
or
“http://www.mysite.com/uploads/picture.jpg”
or
“http://www.mysite.com/picture.jpg”
Is there a plugin or some hack that will let me hide the “wp-content” from showing up in my urls?
