title: Gimp: How to create
body: <p>I'm working on a website design in gimp. I really love the figures and math equations at University of Iowa's stats website (http://www.stat.uiowa.edu/). I would like to create something like this, perhaps do handrawn equations and figures and scan it in. </p>
  
  <p>Once I have the appropriate image, how could I turn it into a transparent image that I can overlay onto a header (in gimp)? </p>
  
  <p>Thanks</p>
