Where should image proxy reside in a MVC structure? (PHP)

[yopee]

I'm trying to get to grips with the MVC structure and trying to decide where my files should go. I have a php script which reads an image from a non-web accessible location and outputs it. Does it belong in the Controller or the View? Likewise, should a script that loads a smarty template (from the view) and sets values and output it be within the Controller or the View?Thanks for your help!
