My thoughts exactly, those are the images I typically search. Wikimedia commons does seem to have a bot (and/or some kind of manual process) that collects some of the creative commons photos from Flickr, but not all of them, even if they are good photos that are well-tagged. I usually search both sites, so I have a good sense of how often a photo appears one on site and not the other. Incidentally, it would sure be nice if Wikimedia commons allowed you to filter by license type.
I do hope some bot out there is collecting and archiving Flickr's creative commons photos before they disappear for good.
