Variable for product slug

[bluecafe]

Hi experts,

does anybody know how to get the variable for the product slug?

I want to get the link to the product image if .htaccess is enabled.

 

This would be something like

$image_path = $image_folder . "/" . $product_id . "-" . $attribute_id.

"-" . $image_size . "/" . $slug;

 

How can I get the slug variable?

Any tips are much appreciated .. thanks!
