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.

Proportional Image Scaling

This plugin is an attempt to prevent distorted images when a CSS max-width rule is in effect and the image is inserted using the visual editor.

NOTE: The wp-admin interface for this plugin still needs some sprucing up. 
I (blobaugh) no longer have access to Windows Azure to continue improvement. If you need this plugin consider contributing to it, or getting me another Windows Azure subscription to continue development.
The Windows Azure cloud platform provides some very powerful scaling ability, 
however natively Windows Azure does not know how to scale applications. 
This plugin teaches WordPress how to scale your website on the Windows Azure 
platform and take advantage of the full power of the cloud.
