Where Are the User Pictures?

I have 4 machines running Windows. Two of them run Windows Vista, and two of them run Windows 7. One of the Windows 7 machines runs Windows 7 Home Premium, and the other one runs Windows 7 Pro. This question related to the machine running Windows 7 home Premium, Version 6.1 (Build) 7600. On that machine, I have set up an account with a "User Picture" from the choices that Windows provides. It is a picture of an Origami Crane (folded paper bird) with a pink spotted skin, like a leopard. I would like to use this same user icon on my other three machines, since it is just perfect for me. Where are the user pictures located in the file tree? I have searched through the tree and have not located the icon, and cannot right-click to copy it! Please help, thanks.

 

They're at C:\ProgramData\Microsoft\User Account Pictures.
