Could we put tabs on the tops of the infoboxes that allow different pictures? e.g. s1 for series 1 picture, s2 for series 2 picture and so on - it'd be a way to show - since the articles don't use pictures - how the characters have evolved and aged.
Here is a start, not sure how to nest it in an info box.
Update: check it now.
Yeah, that'd be it; then, we can do it for all characters to show how they've aged and changed.
What do you think?
