I'm fairly new to creating a wikia and I am having trouble figuring out what I'm trying to do. So my wikia is on a game which focuses on collecting costumes for characters. I have a costume page for each costume and these pages have an image, however because the point of the game is to collect these costumes to see them, I feel like the images are a bit of a spoiler so I wanted to add a Spoiler Button which once pressed, disappear and be replaced by the image. The template for my costume pages is here.

So what I'd like is a Button to be in place of my current Costume Image and then once clicked be replaced with what I currently have. The closest I got to it was this, but I'm unsure on how to edit and use it to suit my need. I also already know about the Show/Hide Button but I want a Button that is able to be replaced with the image instead of a toggle button which stays.
