Wikipedia:Icons in infoboxes

An infobox should contain information pertinent to the subject in question as a whole. If a logo is frequently identified as being representative of the topic as a whole, it should be placed at the top of the infobox. Other logos that are owned or representative of subsidiary subjects should not appear in the infobox, most especially if they are "iconized". This increases visual clutter in the infobox, detracts from the purpose of the infobox, and creates misdirected understanding of the topic.

This issue is independent of the copyright status of the images in question.
