I used a template from Litmus with an image background and a text overlay. Everything looks great in Pardot (the automation platform used at my company). However, after I send to myself or anyone else as a test the image either doesn't show up or is compressed oddly. The image is also not showing in the view in broswer link.

        <table style="background-image: url(http://d2lx8oeagiceqf.cloudfront.net/content/HDS_ePhero.png?mtime=1461361393);" class="wrapper" height="442" align="center" background="http://d2lx8oeagiceqf.cloudfront.net/content/HDS_ePhero.png?mtime=1461361393" bgcolor="#00703c" border="0" cellpadding="0" cellspacing="0" width="640">
