Windows 7 Profile Default Image Files Location

I'm looking for the location to the images that are used next user's accounts when a user logs into a windows 7 system. Can someone point me in the right direction.

The following is a screenshot of the pictures I'm referring to: enter image description here

Need the location so that I can add/edit/remove images via a program (E.g. Different icons for different employee types.)


Not really a programming question, but the location appears to be C:\ProgramData\Microsoft\User Account Pictures\Default Pictures.
