Images are saved @2x for retina optimization and then displayed at 1/2 their true size via width and height attributes. Outlook on Windows seems to strip the width and height attribues (and inline width/height styles) and replaces them with the actual dimensions of the image, doubling the size we want to display.

This:

<img src="http://www.acme.com/assets/images/logo-retina.png" alt="logo" width="408" height="48" style="width: 408px; height: 48px;">

Becomes:

<img src="http://www.acme.com/assets/images/logo-retina.png" alt="logo" width="816" height="96">

Is this normal behavior? Any way to fix this?
