(I may have categorised this wrong, If so, I apologise)

div class=NavFrame and div class=NavContent are used to create the expandable infoboxes widely used on Wikipedia.

However, they have odd handling of other images in both IE and Firefox.

http://en.wikipedia.org/wiki/Agrippina_(opera) is a good example: The "George Frideric Handel" infobox in the upper right of the page can be expanded to show his operas, oratorios, or cantatas.

However, in IE, doing so causes everything on the page to be pushed down, and in Firefox, the images - including the ones on the *left*, which shouldn't be affected - are pushed down.

This is not graceful handling, by any means.
