set root folder??

[dajohnson1s]

Hello,

 

I am wanting to setup a configuration file for my application that points to where images are located.  What I am trying to do is have the images go to the 'root' of the folder to access these images to load in sub folders.  I would imagine this has been done, or this is a function to do such a thing...

 

Here is my structure:

root

|-img

|-admin

|  |-folder

|  |  |-application.php

|  |  |

 

Basically I would like one place to update if the image folder is moved.  Any help would be greatly appreciated.
