I'm sending a newsletter using a mass email system (activate direct). The header is a PNG with transparency. It works fine in everything but IE (and outlook, etc., I'd assume)
I'm not exactly sure why, but the only way I can get the transparency to work properly is with Microsoft's solution linked to below. The other javascript and php-based solutions provided by a Google search don't work. Obviously Microsoft's ActiveX based solution won't work at all in Safari, Firefox, etc.
What I need is a way to selectively display the image in a normal way when the browser is Safari, Firefox, etc., but to use the ActiveX method when IE is detected. Is there a way to do this?
