I took the specific photo of a cassowary (quite splendid) off my blog, plus another one that appears to be from her.  I would encourage you to look at her gallery as she does excellent work.

Last night when I googled myself, which is not a sign of narcissism as much as self-defense, and discovered that the University of Calgary Press book of mine, "Bronze Inside and Out" is available as a pdf or some other kind of knockoff at a dozen urls.  So far the Press has not sent me a royalty statement or any money earned.  Last year I earned about $5.  The statement is supposed to be sent in March.  All my self-published books at www.lulu.com/prairiemary have popped up at Google -- not Google Books.

In the Sixties when Bob Scriver's work was pirated, all of it carefully copyrighted, they told us the law is unenforceable unless you have very deep pockets.  It is a function of international agreements and nations no longer defend them.

But I don't want to interfere with an artist, I do not fall under the protection of fair use for education purposes, and it's a lot of work to illustrate my blogs.  I'm considering the idea of just not using illustrations.  I'm in it for the writing anyway.  And I don't even bother to copyright it.  What a fantasy.
