Request Ability to "Clear Floats" on Articles

In maximizing the web browser to a modern-day resolution, many pages with floating screenshots start to look bad. The images stagger. 
 
Case in point:
 http://www.giantbomb.com/fallout/61-11704/
 http://www.giantbomb.com/dr-mario/62-1073/
 
What I'd like to request is an option under the INSERT menu is to have a 'clearfloat' term, or to give the screenshot the option to clear floats, or else to just make floating screenshots clear floats by default.
 
Or is there another way to fix this with the current setup? Thoughts?

Can be solved by using tables with invisible borders.
