If you really want to not see the image for whatever reason, just use the “spoiler” feature on one of the tags (you don’t even need to hide the tag) and the featured image will vanish from the front page.
I just tested it out of curiosity to see if it would work.
Something I’ve just discovered: You can’t hide a featured image while it’s still on the homepage.
It’s nothing against the artist, because the picture is very well done. It just makes me uncomfortable.
please note that Fluts is making sure that Angel only handles the relatively harmless millipede and wolf spider while she herself handles the actually dangerous critters
