For custom badges you just need to "upload a new version of this file" after uploading a temporary image in the "Customize Badges" page. You can see an example here under File History: https://disney.fandom.com/wiki/File:Badge-luckyedit.png

However, I don't believe the CBS wiki even has achivement badges enabled. You'll have to ask staff for that first.
