What i want is to have a field called Manufacturer so the user can select the product manufacturer. The way to show the field is an image linking to the Manufacturer page.
example: Product "door handles 0001" has a Manufacturer Audi.
I'm thinking using taxonomy terms with one more field in them (image) but when i import the field just show the name linking to the taxonomy term not the image.
I have see that stackexchange but i can't manage to do it, the patch is a little outdated..
The easiest answer to your problem might be the taxonomy image module:
"The taxonomy_image module allows site administrators to associate images with taxonomy terms. With the association created, an admin can then make a call to 'taxonomy_image_display()' from their theme or other PHP code to display the appropriate image."
but since you already have a field associated with your taxonomy term, you just want to suppress the output of the tags in your node template and replace it with code that loads the term field and then renders it, ex. roughly:
/* load your term object */
$term= taxonomy_term_load($node->field_tags['und'][0]['tid']);
/* load the entity object (your field names will vary)
$result=field_view_field('taxonomy_term',$term,'field_image','image');
/* display the rendered result, this can be set in manage display for your field to use image styles, etc. */
print render($result);
