Maybe the question needs to be adjusted a bit.
Rather than "Are these snakes worth it?".....because the snakes are worth whatever you're willing to pay for them...their value is defined solely between the seller and the buyer.
A better question to define the discussion thus far would be "What is the risk to buy from someone who would use this kind of picture to promote his business and is it worth that risk?" The answer to that question will differ between many people.
