I'm with you jnanian. My sister ran a small press for a while, put out small bunch of books that they thought should be out there. I gave a few images to them, and did some copywork for them from time to time. Why is this automatically a problem if all parties involved are satisfied? Is using a friends labor to repair your porch instead of a pro contractor a problem? Worse if the friend s happy to do it in exchange for a six-pack of beer instead of $750? As stated- it was a call not a requirement, and I expect there are plenty of people who would be more than happy to have an image on a book cover- even if it is some little publisher.
Because helping a friend is a lot different than a stranger who is in business asking you to give services to his business for free. Not hard to understand.
