Show image thumbnail or site video as soon as you enter site url

1

I have a post system, but if I put for example: " link " the system will interpret this way and it will print like this. I would like to know how to do before the user posts, a preview of the image or video appears and after that post, appear as an external image or external video. Just like on Facebook.
