Generic social share button issue

[Ozzee]

Hi everyone
I seem to have an issue with the social share module for products that comes built in with prestashop. When I click on a product, then click on the facebook icon to share that product, it doesn't share the picture of the product or the product details, it shares the website and some other picture on there. 
I've looked at the config for the module and cant find any setting, and searched the forum for related issue but found none.
I'm a noob so I apologise for this small glitch I can't seem to fix.
