Generally, when we share a link on Facebook, it fetches a preview. What I want is that when users share their referral link from my website the preview fetched should be an image. Look at the examples below. The one which fetches an image. https://dollartube.ositracker.com/92606/7380
The one that doesn't fetch the image https://www.dollartube.com/index.php/signup?ref=ab93974134f7b971
Is it possible to change the link so some image is fetched as a preview? I believe it is something we can control. Just not getting the idea where to start.
