You can insert a background image into a table cell. The image must be hosted by Campaign to use it as a background image.

1. In the source view for the email, locate the image that you just inserted.
2. Copy the following image attributes and values: src, name, contented, spname, and xt.
3. In the table cell tag <td> where you would like to place the background image, paste the image attributes and values.
4. Change the src= attribute name to the background= attribute. Also, change xt='SPIMAGE' to xt='SPCELL'.

Your table cell tag should look like this example:

<td background='bgimage.gif' name='bgimage'
contentid=405a01-11e89923788-4f4749e15ce6d7a21b02ab08b9b7921c xt='SPCELL'
SPNAME='bgimage'>
