They are in a box thing and can have a picture attached, but I have no idea how to code this. My Wiki is Weebipedia. I will continue working on this to see if I can figure anything out. Any help will be most appreciated!
That template is using table markup. Help:Tables should help for that. It's also a good idea to observe template code itself and see if you can manage copying it to your wiki and customizing it to fit your purpose. :)
