To find the pages of those images and the content of the Web page is not an easy thing, the page has a variety of pictures, ads, recommend other pages of thumbnails, logos, etc., but in relation to the Web page less and less pictures.
In the past, we all felt that there was no need to have words enough, but to the information explosion of the era, the face of huge web pages, people have no interest. The first one has to face this problem is the social networking site, people in addition to their own tweets, more time may only be in the microblog, sharing the page . If you have a thumbnail of a Web page, you may be able to dramatically increase the likelihood of a link being clicked, which in turn will increase the activity of the site (which is, of course, a blind guess).
It is not impossible to find such a picture from the Web page, which takes a lot of experience (CPU-intensive), and is not perfect, not guaranteed to find the picture is 100% correct.
So the boss of Facebook's most global social network has proposed an open graph program. In the head of the page, plus <meta> tags, to pass the page's keywords, summaries and other information, including a thumbnail image.

This is what the encyclopedia explains.
The
Open Graph Communication Protocol (PROTOCOL) is itself a set of metatags specifications used to annotate your page and tell us what type of real world objects your Web page represents. Another partner Web site, Amazon's Internet Movie Database (IMDb), will use this open Graph protocol to label each movie page. Press the "Like" button on the IMDB to automatically add that movie to the "Favorite movie" in Facebook user profile. Facebook has partnered with Yahoo and Twitter to adopt the OAuth 2.0 certification standard. The Graph API has revamped Facebook's platform program code to give every item on Facebook a unique ID. Connecting networks built by other social networking sites through open graph will create a smarter, more socially connected, more personal, and more semantic-minded network.
Although the Internet does not have a national boundary, it is regrettable that only the most socially-genetically-connected Sina has joined the Open Atlas program in China. That is to say, in China this way won't work.
What's more, if you're looking for a web-related image, the site will never match you. Almost every website uses a completely different structure to display text and pictures. If you want to find an ultimate solution, you'll have to look for another way.
