Great gem for attaching images to a rails app (maybe even Laravel). This article made it clear how to set this up

And this one made it clear why my development environment was not working.
I had to edit my .bash_profile
But instead of restarting the terminal I just didĀ 

source ~/.bash_profileĀ 

and then started that rails server again in that terminal.

If only I found a tutorial on using fog and paperclip since I am already using that gem for refinerycms
