OT: Grabbing website thumbnails

[eluser]Daniel H[/eluser]
This is OT for CI, but does anyone know how Facebook and Digg grab thumbnails from a given URL, allowing the user to illustrate their share/submission?

You could use cURL (if installed in your php) to read a remote files contents. Below is a good link to something similar you are talking about with images:

http://curl.haxx.se/libcurl/php/examples/resizejpg.html

Or you can use fopen as well but from memory cURL is the safer option.

Is there any fast and Free solution with a class or something. From which I can get the thumbnail of the page of a given URL?
