Yotophoto seems to have improved since the last time I looked at it: http://yotophoto.com/search?kw=wikimedia+commons They link correctly to image description pages rather than raw images.
They say "Originally an experiment to facilitate easier image searching of the Wikipedia, Yotophoto eventually expanded to index other well known free image sites." I didn't know that... Anyone know how to do a site-specific search there?
Because of Wikipedia's habit of having the "fake" image page when using an image from Commons, I suspect we will languish in anonymity for some time yet...
