Rendering of big image inside a small box

This is a non critical bug. The following syntax

(% style="WIDTH: 334px; HEIGHT: 82px" %)
(((The following illustration depicts the overall physical architecture of the solution.

[[image:output_html_m5008434e.jpg||height="444" width="496"]])))

Has the issue or rendering the image outside the box. The rendered has a <div> with the width and height set to 334 and 82px. The image is bigger and renders outside.
It does not look good.

Shouldn't we use an overflow: hidden or scroll to avoid it looking awfull (it will only look bad with that overflow setting). And should we have a class=box on the div so that we can more easily change it's style.

This is not critical because I think only IE6 allows to resize the box in the wysiwyg editor. It happened on a customer use case because we had some unwanted boxes coming from the importer.
