Gedday – the code suggested above worked beautifully in the designer, but it seems some email clients can’t handle it (gmail being one of them). Any suggestions??
Code:
<style type=”text/css”>.mcnTextContent img { max-width: 100% !important; }
</style>
(FYI – I’m actually using an older WP Images plugin as I don’t have authority to change site settings. Might this be my problem?)
