Photos of dead children are not okay.
I refer to the tragic story of Nate the toddler (https://au.be.yahoo.com/lifestyle/real-life/a/34336837/must-read-the-moving-story-of-toddler-nate-yahoo7-be/ ). I read his moving story, only to be confronted with a private photo taken by grieving and devastated, not to mention vulnerable parents. It's great to raise awareness about accidental drowning, it is counterproductive to show photos. Consider your audience who may well have had bereavements of their own to whom this is incredibly distressing. Please give some humanity to your service and consider your content. I respectfully request you please remove the photo, or at least put a distressing photographic content warning on there.
