I think the first fair use criterium should be more clearly written: it seems that many people think that the part about a replacement which could be "reasonably be found or created" excludes the variant of getting out of the house and taking a picture. :-)
I've been tagging as replaceable a few hundred fair-use images of public buildings.
There were quite a number of images which had the "no free alternative found on the internet" as fair use rationale.
Also, so far, I got one disputation:
<< I have looked for a free alternative of this image, without finding one. No luck on Flickr or Google. Short of forking out for a digital camera and going to take the image myself, I can't see how "a free image that provides substantially the same information might reasonably be found or created".
