How can I achieve this:
screenshot (I don't have enough reputation to paste the image here :/ )
On Facebook & Google and many other websites, when your post includes a link, it displays an image from the website's images. This makes the posts look better.
I have no idea how to do it (I don't even know how to tag this question XD) . I'd appreciate any general directions about what to investigate. Is it something Jquery can do?, should I try find a library (I use django)?, Is it complex?
