This question was asked here: How to handle potentially NSFW yet valid images
I'm looking to provide a formalised protocol that may be added to the
FAQ for Stack Exchange sites.
I've asked this question on Pets.SE:
Within it are very graphic photos of an injury. The photos are hidden - so that they can only be seen with a hover.
I've included large warnings using headings, but I'm fearful people may hover accidentally over these images.
The images are relevant, as the answer will show the story of the recovery (I haven't posted the answer at the writing of this, as I want to post many images in the answer). The question and answer will also be highly useful.
I'm looking for a canonical answer, so we can advise people what's the best way to proceed with such cases.
Is it ok to format such posts as I have or should these types of images be linked externally, so there's no potential to hover?
