Twenty Ten Bug Found – Image Resizing

We noticed an issue where images wouldn’t properly resize when viewing a post (they resized properly in the editor). It turns out a number of people are having this issue. Here is the culprit:

#content img {
	margin: 0;
	height: auto;
	max-width: 640px;
	width: auto;
}

The height and width entries are overriding the tag attributes set by the resizing editor.
