Add custom route parameter to product URL

[mgr_metal]

Hi,

 

I would like to modify my product url to look like this:

 

{category}-{id}-{rewrite}-{image_id}.html

 

Where image_id is a custom string that indicates image id from fotolia.

 

So my question is how can I add custom string to my product url?

 

 

update:

 

I dont know if Im doing it right. 

I would like to integrate fotolia with prestashop.

 

My idea is that I added categories to prestashop like "City", "People" etc. and when someone

click on that category fotolia pictures are displayed by api.

 

In my shop I would like to have few products like: "painting", "stickers" etc

 

How to easyly connect fotolia picture with product?

 

 

Thanks in advance!
