Implementing a pop up window
Implementing centering feature for image downloads - Pop Up Window

I posted [here][1] asking a coding question on face recognition.  How do you get an x by y image to an x by x image.  The answer was easy let the user do it, this is how facebook does it.  I want to implement this as well.  

The user uploads the image durring a one step sign up.  I want a pop up window to ask the user to center the image before taking them to the start screen.  How do I implement a pop up window with out using libraries?
