Image copywrite issue – any tools to help??

We have a website that has a potential issue with copyright around an image. Because of this we want to do a whole audit on the website, looking at every single image and checking to see if it has a source listed. 

I would like to be able to use a tool to scrape all of the images on a WordPress website, and then have that tool. Tell me which pages have that image. 

I don't know if that kind of a tool exists though.
