I've followed this tutorial to put together a html signature for Apple Mail http://gatheringinlight.com/2007/12/03/how-to-make-an-html-email-signature-for-apple-mail/ So I've tested it with this simple file: <div> <img src="http://www.mywebsite.nl/logo.gif" width="283" height="34" /> </div> This should just display the logo. I've saved this through safari as a Web Archive file and saved in onto the Web Archive file of Apple Mail in the Signatures folder. Then opened Apple Mail again. As you can see, while composing the mail the icon turns into the blue question mark icon. I've later sent it to my private email address and it arrived as an image. Why won't it appear in the email while composing? The various tutorials about html signatures display any image already there while composing the email. So I wonder why it doesn't on my Mac.
