I am using attachment\_fu to create thumbnails, and it is working  
great. However, I am have a view with all my users thumbnails  
displayed and am trying to make it so when you click on a thumbnail of  
their avatar, it shows that users profile. In order to accomplish  
this I have saved a user\_id identifier for each avatar, but the  
problem is that attachment\_fu only saves this user\_id for the main  
image and does not save it in the column for the thumbnail. So when I  
try and access the user\_id to display the corresponding profile, it  
says the user\_id is 0 and there is no user with that id. Is there any  
way to get attachment\_fu to save the user\_id to the thumbails too?  
Perhaps there is some other solution. Heres the code for the avatars  
so you can get a sense for what I am trying to do:

\<% for avatar in @avatar -%\>

\<%= link\_to image\_tag(avatar.public\_filename()), {:action =\>  
“index”, :controller =\> “users”, :user\_id =\> avatar.user\_id } %\>

\<% end %\>  
So this user\_id is 0 b/c the attachment\_fu didnt save the user\_id

Any ideas are greatly appreciated. Thanks, Dave
