User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b) Gecko/20050127 Firefox/1.0+
Build Identifier: Thunderbird 1.0 (20041206)

In an HTML signature file, <IMG src=""/> references are converted to attachments
and sent with the email (see Bug 127077) and apparently <BODY background="">
references are too (see Bug 116867). However <TABLE background=""> references
are left as-is, as are CSS style="background-image: url()" references.
I've used both file:/// and http:// URLs, both with the same effect.
My current signature uses a table background image and also an <IMG/> image and
only the <IMG/> is converted to an attachment, the other is left as a URL.

Reproducible: Always

Steps to Reproduce:
1. Create new signature file
2. Enter text:
<table background="http://www.mozilla.org/images/firefox-oneoh-top.png">
<tr><td>A silly signature table with a background image and an in-line image
<img src="http://www.mozilla.org/images/thunderbird-screen.png" hspace=10
vspace=10/></td></tr></table>
3. Send email to yourself, save and check source. You get a <img
src="cid:part..." for the in-line and you get the original background="http://
for the table. Same effect if you use style="background-image:
url(http://www.mozilla.org/images/firefox-oneoh-top.png)" in the <table/>
instead of background="".
This is actually two bugs -- one about copying the attribute from style to 
background attribute (should be unnecessary) plus not converting the URL in the 
style to the cid:; the other about failing to attach the image (and convert the 
URL) for the <td> background image.

Reproduced both problems with TB 1.0 and Moz 1.86b-0120, Win2K.  Interestingly, 
I notice that -- with "do not display images in mail" pref checked (and 
whitelisting turned off for TB) -- when the <body>'s background attribute has 
been set to a cid: URL, but the style attribute's background-image property is 
still the external URL, that there is no background image shown: the style is 
overriding the 'background' attribute.

Bug 234252 and bug 253222 are related to the style/attribute confusion.

The second problem has been reported, as bug 277925, now confirmed.  Focusing 
this bug on the first problem.
Summary: Table background image and CSS background-image not sent with message → CSS on mail <body>: background-image url not converted to cid:
sorry for the spam.  making bugzilla reflect reality as I'm not working on these bugs.  filter on FOOBARCHEESE to remove these in bulk.

I get no cids and now images as attachments.

Thunderbird 52.0.1 (32-bit)
Windows 7 64-bit
That should have been "no images as attachments".
Severity: normal → S3
