This request has been status-declined because it was scoped as a way to show only Dominion cards. That's not what I'm looking for.
Then there's this user script that works only for MtG cards. That's not what I'm looking for either, I want to be able to mouseover any image.
What I'd like to be able to do, is to include images in a post (same way we do already, using imgur), except then hide the images behind a mouseover.
This can be used for Dominion, Smash Up, Yu-gi-oh, Pokémon, Catan, Stone Age, Fluxx... anything with cards. Experienced players won't need this information as they know the cards, so including them takes up unnecessary space.
For example
Right now we have a way of embedding images, using this syntax:
[![Monopoly Money][3]][3]
[3]: https://i.stack.imgur.com/OiWePm.jpg
Also we have a way of embedding hyperlinks, that works like this:
[Monopoly Money][3]
That becomes this:
Monopoly Money
I guess what I want, would look exactly like the Monopoly Money hyperlink, only if you hover your mouse over the hyperlink it shows you the picture without having to click on it.
[my image](https:www.foo.com/image.jpg)
would become a hover-over link. It doesn't matter whether image.jpg is "official".[dominion:Village]
