A few I've found in the last half hour.
btw a handy tip if you didn't know if already. If you come across a profile which is set to private (most of them) right click on their profile image and select "View Image". You will see in the address bar the users id eg profile.ak.fbcdn.net/v22939/1565/10/n
12345678910_2569.jpg the bold part is the user id.
Now copy and paste that id at the end of this address:
http://www.facebook.com/photo_comments.php?id=xxxxx where xxxx would be the user id.
This will now show you any photos they have which have been commented on. Click on a photo and then you will be able to see the rest of the album.
