How add image to manucfacturer programmatically

[ricky250r]

Hello I have done several search on the subject without finding answer to my problem. To add a brand I have this code that works but my problem how to add an image has my brand. What should be used to have all the image formats needed.

$date_jour = date("Y-m-d H:i:s");

//créer une marque
$manucfacturer = new Manufacturer();
$manucfacturer->name = 'Test';
$manucfacturer->active = 1;
$manucfacturer->date_add = $date_jour;
$manucfacturer->date_upd = $date_jour;
$manucfacturer->description = '';
$manucfacturer->short_description = '';
$manucfacturer->add();

Thank You
