Yes I agree with what Stas says, which is why I posted my invitation. Also, we have many more items without images on Wikidata than Wikipedia articles with images, so we also need illustrations for things that don't have a page on Wikipedia yet such as everyday items (cookie types), minor paintings, minor monuments, or minor politicians, etc. As far as fair-use images go you can't link to them with the P18 (image) property because that only points to Commons. I have in the past linked to a Matisse painting on the English Wikipedia with P973 (described at url) link. For people who are interested in linking WLM or other monument images, they may want to start with the handy nearby feature in Wikidata (left side of the screen).
