Hi all,

I’m trying to use attachment\_fu with a facebook app - I have a challenge  
when I go to call an image:  
\<%= image\_tag @photo.public\_filename %\> renders:  
 ![](https://www.ruby-forum.com/my_app_name/photos/0000/0005/Picture_8.png?1194210310)

This is because the way I have my facebook set up is to always prepend  
the path with /my\_app\_name/

I added this to environment.rb as specified in the rfacebook tutorial on  
Liverails:

ActionController::AbstractRequest.relative\_url\_root = “/my\_app\_name”

any ideas on how to get around this?  
Thanks,  
Dustin
