Creating Background Images when content flows onto the next page

[Larene Spitler]

I followed example 51 to set the image after $pdf->AddPage();

I am using
$pdf->writeHTMLCell(0, 0, '', '', $para, 0, 1, 0, true, '', true);
to write the content and it goes beyond the first page.

What do I do to get the background image on the rest of the pages?
