People are giving you the right answer - you can't be picky and lazy, too. ;-)
If you use a half-baked solution, you'll deal with a lot of edge cases. Here's a working sample that gets all links in an HTML document using HTML Agility Pack (it's included in the HTML Agility Pack download).
And here's a blog post that shows how to grab all images in an HTML document with HTML Agility Pack and LINQ
// Bing Image Result for Cat, First Page
string url = "http://www.bing.com/images/search?q=cat&go=&form=QB&qs=n";
// For speed of dev, I use a WebClient
WebClient client = new WebClient();
string html = client.DownloadString(url);
// Load the Html into the agility pack
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(html);
// Now, using LINQ to get all Images
List imageNodes = null;
imageNodes = (from HtmlNode node in doc.DocumentNode.SelectNodes("//img")
where node.Name == "img"
&& node.Attributes["class"] != null
&& node.Attributes["class"].Value.StartsWith("img_")
select node).ToList();
foreach(HtmlNode node in imageNodes)
{
Console.WriteLine(node.Attributes["src"].Value);
}
