Hiding Image URLs (Rails 3)
**BACKGROUND:** Each user has their Facebook profile image URL associated with their account. This image is called using `<%= image_tag(@user.facebook_image_url) %>`. Each user's Facebook URL takes the following form: http://graph.facebook.com/123456/picture - with 123456 being the user's particular Facebook ID number.

**OBJECTIVE:** I'd like to prevent other users from being able to figure out who the user is simply by right-clicking 'copy image url' and looking at the ID in the image URL. 

Is there a gem/plugin or better way to accomplish this other than downloading the user's image from Facebook's servers?
