We are using the copyright images under the fair use clause of U.S. copyright law copyright.

There is a whole lot of legal mumbo-jumbo involved, which you should ask a legal expert to explain. IANAL, but basically, it means:
 * 1) If Zynga stops consenting, or asks to remove the image(s), at any time, we would have to stop or remove those images from the wiki (or face legal action)
 * 2) We have to attribute the images properly (the "copyright Zynga" information under the image)
 * 3) * The image page should use the template Fairuse
 * 4) We can't overuse the images, such as using them solely for decorations, they have to actually be relevant to the page where they are used

And yes, as James said, Zynga is at least nominally aware of the wiki. As an (unofficial) fansite, our use of copyright images is generally ignored, but we still need to be careful not to abuse copyright.
