从网址中检索图片

Question

On my ASP.Net page in C#, the user is able to enter an URL (web page). When it's done, I would want to get the picture in this page. For an example of this, go on Facebook and write a status with an URL in it. A panel open with the description of the page AND the picture.

Is there a parser or a little application that I can use for this?

Look at this post for code on how to retrieve html DOM from an url . Once you get a reference to the IHTMLDocument3 instance, use the getElementsByTagName method to retrieve all IMG tags, and take the first.
