I apologize if this has been asked before, but does anyone know how to add tabs to infoboxes? I've copied codes from various wikis and pasted them to my infobox, but there always seems to be a problem, whether it be unnecessary bits of text, images not showing up, or there being no option to resize an image.

This is the box I want to add tabs to. Is it just a matter of where I paste the code, or is it something else entirely?
