I definitely had a mild reaction to that sort of image, long, long before it was discussed anywhere. My first instance, as a teenager, was where I had found a lump of play-doh, and (for whatever reason) jabbed it repeatedly with a pencil. I was then disgusted by what I had created. My second early incident was seeing the cover of the O'Reilly book "Windows Annoyances", which features an image of a Surinam toad with young embedded on its back. Yes, I wasn't a fan of Windows at the time, but I couldn't imagine what the editors were thinking when they chose that cover image.
