Img15 (Windows 7)

img15, originally known as Germany, Dusseldorf, theatre, is a wallpaper included in Windows 7 as part of the Architecture theme, licensed from Corbis. It was taken by Gregor Schuster, who also took Windows Vista's usertile7 user account picture. It depicts the Düsseldorfer Schauspielhaus theatre in Düsseldorf, Germany.

It originally came from German stock photo agency zefa, which Corbis acquired in 2005, which in turn was acquired by VCG in 2016 and had its images moved to Getty Images. However, it was taken down from Getty in 2020 and is no longer commercially available.
