Hello @AjeetV ,

That information is what the social site chooses to display for their link previews, and isn't something we or you can control. If you're wanting a different image to be displayed, we'd advise including an image of your own in your post, which should override the platform's link preview functionality. Otherwise, you can also prompt the platform to not show the aut-generated preview, when setting up the post as an actual social post (not an email share).
