If you include any reference to a URL, your entire declaration will be ignored.
For example:
background: #000; /*This will be accepted */
background: #000 url(http://www.test.com/test.jpg); /* This entire line will be ignored */
With that said, if you ever want to back up your background image with a color, be sure to do it within a different inline CSS declaration.
For example:
<td style=†background: #000; background: #000 url(http://www.test.com/test.jpg);â€>
To get background images working in Gmail, try using the “background†attribute within your TDs.
<td background=“http://www.test.com/test.jpg†bgcolor=â€#eeeeeeâ€>
