Subject: | cid has no effect on background images |
When I specify IncludeType => 'cid', images are embedded by using the
"Content-ID" header. However, background images specified by CSS are not
treaded that way: they still remain their original url.
For instance:
<div><img src=images/blue.gif>This image is embedded with cid
correctly</div>
<div style="background-image:url('images/blue.gif');">This background
image is not shown in IE</div>
As a result, e.g. Internet Explorer does not show the background image
from the second <div>. If I change the url in the email into the
cid-header from the first <DIV>, the background image is shown correctly.
