title: images in upload directory after upgrading WordPress to 3.0
body: <p>I've developed a <a href="http://wordpress.org/extend/plugins/my-record-collection/" rel="nofollow noreferrer">WordPress plugin</a> and it wordked well from WP 2.0 and up to WP 3.0rc1 (haven't tried rc2) but now with rc3 and milestone 3.0 a strange and irritating error appeared.</p>
  
  <p>If you check out my <a href="http://myrecordcollection.arvid.nu/demo/" rel="nofollow noreferrer">demo page</a> you will se that none of the cover-images is working. they are in the same place as before but they can not be hotlinked or show up when i enter the correct url. if i move the img-directory from /wp-content/uploads/my-record-collection/ to /wp-content/uploads/ the images show up if i enter the url, but not if i move it back inside my "my-record-collection"-folder.</p>
  
  <p>anyone know what change in rc3(or maybe rc2) that made this bug appear and what can be done to fix it?</p>
