I have tried doing the following - to create a landing page using the Clickthroo service, and then post a link to this page in a facebook post. The problem is - there is no image preview popping up for this link. I've done some research, did the facebook debug for this link and gotten the message like: "Failed to get composer template data." Then I found that it looks like facebook is intentionally blocking some of the image sources to pop up in posts. Does anyone know how to overcome that? Basically what I am trying to do - is to make my link posts to attract more clicks. Would be great if the links could be embedded in the images and would run when the user clicks the image - but I am not sure how to do that either.
