The question asks, in short, "How can I improve the wording of this puzzle?". Most of the answers address this question by providing wording suggestions. This is on-topic for the site; puzzle-creation and preventing confusion in a puzzle's presentation fall under our scope.
However, there is one answer which solves the puzzle without addressing wording at all. I do not think this is an answer to the question as posed. From the three Looks OK votes in the review and comments on the answer, clearly others disagree. Since I can't address the thoughts of the reviewers, as sadly I lack the required telepathy for such a feat, I'll deal with the arguments brought up in the answer/comments.
I don't intend to strawman the counter-arguments I present here, but I am going to put all of them and (naturally) some are of higher quality, while some are lower.
From the answer:
I couldn't resist
Wanting to do something which breaks the rules is not, in and of itself, an excuse for breaking the rules. If someone wants to post "Where did you learn how to make this puzzle?" as an answer to a question, that "answer" will rightly be deleted. Moving on to stronger arguments.
From a comment:
I couldn't post a picture that way
As I said in another comment, you can post pictures in comments by linking them. Indeed, people have linked pictures in comments elsewhere on the site.
From the same comment as before:
solving puzzles more closely aligns with what this SE is usually used for
What standard questions ask has no bearing on what this specific question is asking. This question does not ask at all to solve the puzzle. To make an analogy to Stack Overflow, a normal kind of question on that site is a "debugging" question. People will post some code, their goal, and ask how to fix their code so that the goal is achieved. However, if someone posts a question asking about the history of a buggy example in a famous coding textbook (no idea if this question would be on topic, I don't know Stack Overflow's scope well), an answer which fixed the bug would fundamentally fail to answer the question.
From a comment by the questioner
I have no objection to you posting solution(s), in fact, I thought that someone might do it.
If the Stack Overflow questioner from my previous analogy didn't mind the bug-fixing answer, that wouldn't mean the answer was acceptable by the moderation rules of the community it was in. Plus, that's addressing an entirely separate question. (I concede that it could be a "bonus" question, but answering just a bonus is not quite kosher, and is not mentioned in the Puzzling question anyways.) Questions should be focused to have one question so that answers can address just that question; the desire or expectation of the questioner to get multiple answers addressing separate questions is moot.
From a final comment
the puzzle is so charming it’s worth having here
A puzzle being fun to see or solve does not mean that posting a solution to it is automatically acceptable. Again, that has to be what the question was asking. Which, again, was not what this question was asking. A separate question could be created, linking back to the original, which asked specifically for solutions to the puzzle. Then it would be perfectly fine and charming and answering it with a solution would be perfectly fine and charming.
So, is this an acceptable answer? If the answer is “yes” then the correct action is obviously “leave it alone”. If the answer is “no” then should some action be taken (deletion, downvoting) or is this a special enough case that, despite breaking site rules on answers-must-answer-the-question, it should be left alone anyways?
