UPDATE: You might be interested in reading this article: Javascript's way to know the image size.

Find all images under current box, and limit their width to at most the same as current box.

    var w = $(this).width();
    $(this).find("img").each(function() \{
        if ( $(this).width() > w ) \{

This is something similar to always wrap a div around an image. Only it's a piece of un-obstructive javascript instead of over-augmented-semantic-hack-sorting-out-bad-css-box-model.

This generally works good on Firefox, IE7. Didn't try others.
