If there's one image of mine that constantly gets hits, it this:
This was my first submission to Illustration Friday years ago, and it seemed to go over well. I read online about google's reverse-image service, and found quite a few pages using it. Many give me credit, all kept my signature... and almost all kept the copyright notice. Now, I myself have been guilty of posting images I've found on the net on my blog, so I don't want to be hypocritical - but a little linkback WOULD be nice. Therefore, I'm going to place this in the comments of every page I find:
"Hello, I'm Tony LaRocca.
I couldn't help but noticing my drawing on your site, and while I'm flattered, it IS copyrighted. (For future reference, no one has to say that a work is copyrighted for it to be so, although it is clearly marked.) Here is the original 2005 posting on my blog.
Now, as I said, I'm flattered. I'm not going to threaten DMCA action or even ask you to take it down. To be honest, I'm quite happy for the exposure. All I'm asking in good faith is could you please, at the bottom of your post- put the following link:
"Image (c) 2005 Tony LaRocca" and link it to my blog - http://egotisticalproductions.blogspot.com/
Thank you very much. I'm so glad you thought my image illustrated what you wanted to say.
