Get Manufacturer Image on Prestashop

I'm trying to add manufacturer image on **topmenu** module on prestashop. I'm very new to this CMS.
I added this line to the code (`blocktopmenu.php`) to make some tests:

<img src='.$link->getImageLink((int)$manufacturer['id_manufacturer'], 'img/m').'>

Unfortunately checking the HTML generated code, the link I obtain is the following, and it can't retrieve correctly the image I need:

<img src="abtemplates.altervista.org/1/img/m/2.jpg">

But what I need really is this:

<img src="/1/img/m/2.jpg">

**My Question:** Is there a way to obtain manufacturer image with `getImageLink` method or similar? Thanks in advance

You can get the manufacturer image with the following code:

<img src="' . __PS_BASE_URI__ . 'img/m/' . (int) $manufacturer['id_manufacturer'] . '.jpg">

It is more elegant to assign the manufacturer ID to a Smarty variable in the `hookDisplayTop` method:

$this->smarty->assign('id_manufacturer', $yourManufacturerId);

Then you can display it in `blocktopmenu.tpl`:

<img src="{$img_manu_dir}{$id_manufacturer}.jpg">
