P2 on a subfolder…

I have a install of WordPress on my server at JakeSpurlock.com and JakeSpurlock.com/sh/. Everything works great on the main folder, but on the /sh/ folder, I can’t get the P2 media icons to show up. The images for the media icons give me this link: http://jakespurlock.com/sh/sh/wp-admin/media-upload.php?p2-upload=true&post_id=0&type=image&TB_iframe=true which has an extra /sh/ in it.

Any ideas on what I am doing wrong here?
