Conditional Logic to Display Logos

Does anyone know how to use conditional logic to determine which logo (image or URL) to display in a BI Pub report? I was kicking around the idea of using the choode statement but not sure how to wrap the logic around 3 alternate logos that can be chosen. Here is sample logic for the delivered sample data from Invoices:

<?choose:?>

<?when: INVOICE='0000678504'?>

LOGO 1

<?otherwise?>

LOGO 2

<?end otherwise?>

<?end choose?>
