I think there should be some of kind of warning note on every Scooby Apocalypse page, because it's not exactly for kids. Even I didn't like issue 8. I could never go back and cover that properly, it's just too alarming to look at.
I've got an idea. At polish Harry Potter wiki, when you entered the page of some 'Fantastic Beasts' subject, there appeared an all-page wide statement 'This article contains spoilers. Do you want to see it?' and two options to choose: Yes, I want and No, take me back. The thing is that I don't know codes, htmls etc. so we must copy and change it.
English sites, like Disney Wiki, DC Database, and Marvel Database, use the same thing. I was considering using that for spoilers, but the problem with that is, the page underneath still flashes for a couple of seconds, so I'm not sure how effective that would be in the end?
True about the images. And as for the rest, I don't think it would be too bad for here. (As for what can you see in a few seconds? Unfortunate spoilers for Logan on the Marvel Database, which defeated the whole purpose of having a spoiler block to begin with.)
