[VE][108] Howto do table - background=picture.gif ?

Validating http://karisart.se/
Error [108]: "there is no attribute background"

/Line 25, Column 19/: there is no attribute "BACKGROUND".

I have just one error left and I have no idea, so far, how to fix it.
I want to keep the disign.

<table align="left" cellpadding=20 cellspacing=0 width=860 border=0>
<tr><td *background="bild/bg-spiral.gif"*>
    <table align="center" cellpadding=0 cellspacing=0 width=810 border=0>
    <tr><td>
[... Everything on the sajt komes here...]
    </td></tr></table>
</td></tr></table>
