Adding product image programmatically

[Tárraga]

I'm trying to add programmatically a product image with this code

$id_product = $product->id;
$url = 'http://server.com/img/myproductimage.jpg';
$shops = Shop::getShops(true, null, true);
$image = new Image();
$image->id_product = $id_product;
$image->position = Image::getHighestPosition($id_product) + 1;
$image->cover = true; // or false;
if (($image->validateFields(false, true)) === true &&
($image->validateFieldsLang(false, true)) === true && $image->add())
{
    $image->associateTo($shops);
    if (!AdminImportController::copyImg($id_product, $image->id, $url, 'products', true))
    {
        $image->delete();
    }
}

But it seems like it doesn't download image. It adds to product, but no image is shown:

What could be wrong with this?

Thanks in advantage.
