How do I spoiler images for an adult audience

You can mark content (specifically images) as adult related by adding this special command somewhere in your main conversation or comment text.

{media_adult}

The text will not show up but will blur all images until they are clicked.

At this time we don't display a message, but you really should do so in your content saying what the content is, but also edit your account settings so public viewing is turned off or post in a café with public can view conversations turned off.
