Images on background images
I've been working on an email template and stumbled across something a bit odd. I'm using the bulletproof background images from Campaign Monitor http://backgrounds.cm/ and started to work on a header for it when I noticed that in Outlook 2007 and 2010 the background image doesn't render fully like this:
When I view it in other clients its fine (eg Outlook 2011, Gmail, Mail, Thunderbird etc...).
(BTW this isn't the final resting place for the logo, just what I sent for testing the background image was working ok.
Now if I add anything else at all to the <div> that the image is in then all of a sudden everything else appears.
Has anyone else seen this before? I could drop in a non breaking space and it would work but I'm not overly happy on relying on that. By the time I've finish working on the design I will most likely have other things in the header (other logos or a menu) but I want to understand whats happening.
Any ideas whats happening would be great. Thanks.
