Stay polite, and calmly explain where and when the images were released. Avoid words of confrontation - don't say things like "you are wrong", don't start with "why?", don't ask for an outright unblocking,don't even think of calling the block unjust or unwarranted. In fact, don't mention the block at all.

You could frame it as a misunderstanding, stating that you thought it conformed to the rules. Once you've cleared that up, you could bring up the matter of unblocking.
