Comment (by helen):

 I like this - has anybody looked into adding it to other places where
 images are selected, as mentioned in [comment:6 comment:6]? I'm also
 assuming this doesn't work at all in older IEs, which is fine, I just
 prefer to know that something isn't working and where instead of finding
 out later.

 @kjbenk - Not sure I follow what you're envisioning as "just adding a
 border". Do you mind elaborating?
