It's happened to us all at one point. You toil over the design of your newest website project, cross all your t's and dot all your i's and finally complete that mockup for submission to the client. The client is overjoyed! You hit it right on! Oh but wait, he'd like a small change. He has this cute little animated gif of a butterfly that he thinks would look perfect right next to his horizontal menu. Oh and that nice neutral color you chose, he wants it bright yellow.
George Carlin was the first stand up comedians I've seen live, and always something I shared with my Dad as an adult. We watched his TV show together, we went to see him live twice, and every year we exchanged at least one gift relating to his dark and obscene humor.
I recently had a client who told me he wanted all of his images "protected" from being downloaded. My answer was simple: "It's not worth your time to persue that goal". If someone who knows what he or she is doing wants an image, they're going to get it by either examining your code, checking their cache or utilizing their print screen button.
