I use the following to crop and center a picture with css (sorry for inline css but this is just to explain my problem)
<div style="width: 236px;height: 233px;background-image:url('path-to-picture');background-size:cover;background-position:center center"></div>
This works fine on most browsers but I need to reproduce the same in an html email and unfortunately emails clients don't seem to recognize 'background-size'.
Is there a simple way to crop pictures in an html email?
Thanks for your help.
