do you have a video that shows the code or bootstrap for how websites like twitter and facecbook take a link you paste into a status box and display an image and a snippet of text automatically when you share a link?

 

For example

 

i paste this in my email or facebook and i get a picture, a title, author, website and a snippet.

 

 

if not, what is this concept call so i can search for it.

 

thanks,

Greg
