Profile pictures are the pictures that exist in infoboxes on character articles.
Profile pictures must contain only the character that the article is about, their body positioned upright, i.e. not lying down or slouching. Profile pictures are also usually portrait, as that complies best with the shape of the infobox. Any profile picture that defies the above will be swiftly removed and replaced with the previous image. There is no requirement for the infobox pic to be up to date with the series that they last appeared unless the character in the photo looks a lot younger than they are in the series when they last appeared.
Repeated posting of images that fail to follow the above guidelines may result in a block.
Other images rules
Regarding to any image on the wiki including infobox images, images must be of characters as they appear in the show, not of their actors outside of the show.
