When a user inserts an image using the visual editor, WordPress automatically sets the
width and height attributes on the image tag. Unfortunately, when the images’ width is
larger than the CSS “max-width” value, the width is capped but the height is not
affected, leading to distorted images.
This plugin either removes all height and width tags from images of a given class
(resulting in a correct “max-width” behavior) or scales them to a given width to assist
browsers in creating the layout.
