I do once in a while, if I still know who created the content I've used in an image. Most of the time I don't do it, I've got better things to do then try and track who made the content I'm using in my images. I'm creating about 5-10 images a week, most using quite some content in it, so imagine trying to first of all remember who made what, then track down the creator and then contact him. Even then I often couldn't show then the work, since it's made for others.

In the past when I still was creating games I would often contact the creators of the content and often credit their work in the games. But more then half of them never responded, so I stopped doing that, unless I know they do appreciatte it.
