I'll take a stab on this, even tho I'm a bit confused ( or maybe just braindead)..... If you purchased a software product and took a picture of the packaging and used that on your site, then you would own the copyright, however this could potentially open a can of worms in regards to trademark infringement, such is the case Getty is being sued for with the little smelly trees.....more at the link below

Have you been able to locate this image anywhere else? is it widely used? is it available on other stock photo sites?
