Link to Facebook bringing up wrong image

Hi
I have been trying to promote my site via my Facebook page by copying the link in the address bar. However the wrong image is attached to correct link. i.e. Link to enamel necklace and gold earrings image comes up. Totally unrelated.
Is this to do with my Facebook connection or my wordpress set up?
Example of link used
https://mycherrypie.co.uk/?product=enamel-handmade-necklace-with-copper-and-stripe-detailing

Hoping someone can help with this

Thanks
