Manufacturer add logo

[Adrian P. Vales]

Hello.

For this client, we have a module to synchronize the catalog, developed by the supplier company.

This module has a function to add brands for the products. But it does not add images for the brand.

function crearFabricante($NombreFabricante)
{
    if($manufacturer = Manufacturer::getIdByName($NombreFabricante))
    {
        $ID_Manufacturer = (int)$manufacturer;
    }
    else
    {
        $manufacturer = new Manufacturer();
        $manufacturer->name = $NombreFabricante;
        $manufacturer->active = 1;
        if(($field_error = $manufacturer->validateFields(UNFRIENDLY_ERROR, true)) === true &&
            ($lang_field_error = $manufacturer->validateFieldsLang(UNFRIENDLY_ERROR, true)) === true && $manufacturer->add())
        {
            $ID_Manufacturer = (int)$manufacturer->id;
        }
        else
        {
            Logger::addLog('Error añadiendo el fabricante : '.$NombreFabricante, 3);
        }
    }    
    return $ID_Manufacturer;
}

I want to modify the module to obtain the image from the provider's website and add it as a logo to the manufacturer. But I don't see that the Manufacturer class has a logo field.

So does anyone know how to add the image to the manufacturer, by code?
