[TYPO3-english] 2 ID´s in same <tr>

[Cecilie Andersen]

I have a problem regarding an old typo3 site, build in table and autoparser 
(not templavoila)

In a table row I have my menu, defined in typoscript - and behind my menu is 
background a picture - the code looks like this and works fine

<tr>
                        <td valign="bottom" width="955" height="155" 
id="menu" colspan="2" background="grafik/banner.jpg">menu</td>
                </tr>

Now I have the issue that the background picture must be random. I know 
there is a lot of extension for banner rotation, but I am unable to add 
another ID in the same table row, so I can not get this working. If I add 
another ID as below it only show the content of the first ID in the line, 
while the 2nd is not showed.

<tr>
                        <td valign="bottom" width="955" height="155" 
id="menu" id="background" colspan="2" 
background="grafik/banner7.jpg">menu</td>
                </tr>


Anyone able to help with this issue, so I am able to solve this problem

Cecilie
