> Using an image for illustrative purposes is not fair use, is it?
Often it is; the paradigm would be commentary. If you're going to talk about the image, to some extent it's necessary to let people see what you're talking about. Reproducing the Mohammed cartoons ( https://en.wikipedia.org/wiki/Jyllands-Posten_Muhammad_carto... ) in a discussion of them would obviously be fair use.
As with most aspects of the legal system, there is no standard for what is or isn't fair use.
