You need a level of permission, that's why the artist should be cited, if google doesn't have permission, they'll get shit about it, if we don't, we get shit about it and a black eye on the Wiki reputation, especially if the artist wasn't even cited.

If you cite it, at the least the rest of us have a good chance of telling you it isn't OK by looking at the artists page and finding their preferences as far as being OK with free use in a timely manner.
