image wrapping behavior

[metroave]

Is there wikimarkup that controls how images wrap? I know how to align them l, r, c, but I'd like them to stay within a certain heading area and create space below themselves before starting the next heading (==heading==). Here: http://www.hscross.com/wikis/index.p...Michaelmas#Ely the images span several heading sections and I want to confine them to one. Can I do this without a) shrinking the images more, or b) manually adding returns?
Many thanks!

Actually, I just worked this out. I put <br clear="all" /> before the new heading section.
