I am a developer working on a not-for-profit project and wanted to use an image that I found off google, I've searched around but can't find anything about the author/illustrator. Can I use this is in my project and if so, how do I give credit where its due?
Giving the author of a work credit does not excuse you/your organisation from copyright infringement. This is a commonly held belief, but it's false nevertheless. Not knowing, or being unable to find who the author is, or being unaware of the copyright status, doesn't excuse you from copyright infringement either.

Regarding the non-profit thing, I have a true story to tell you. . .
I did some voluntary work for a non-profit community theatre company once. They used the name Peter Pan for a poster for a production based on the story of the work Peter Pan by JM Barrie, without seeking permission, and the copyright owners threatened to sue them. Despite being a non-profit organisation, they had to pay up. The theatre company didn't have enough funds to fight it in court.
When citing sources it is important to follow citation guidelines. Some of the most widely accepted guidelines are from MLA, OWL, and APA.
I believe because your project is Not For Profit you can display the work of others. The specific legality needs to be looked farther into.
