Image float/text wrap/box breaking problem

Hey,

I’ve created some CSS tags with “float: right” etc, like in the Codex example, for aligning images in my posts. The problem, though, is that when images appear on the front page, and there isn’t enough text, the image “breaks” the entry box and goes into the post below it. It looks bad :[

I did find an example of a “clear” tag somewhere, but it has to go after all images in a post, and if you have a post with more than one image and a <more> tag between the two, it won’t help you with the top image, which will still break the entry box on the front page.

Any ideas? I’d like to get this working, cause images without wrapping looks pretty bad.
