Photo background changer. Add new backgrounds

"University of Melbourne alumna Julia Gillard has become Australia's first woman prime minister. This is a matter of even more pride for the Faculty of Arts at the uni (where she graduated in Arts and Law), of which I am a part today. The whole place is rejoicing! Please do this edit job for me — I want to add it to the uni blog. Place an image of the University building in the backdrop of this photo of Julia Gillard taken in June 2009. Thank you."
