If that's really all you have you might get away with a regular expression, like

src="([^"]+)

However, you can't and shouldn't try to parse HTML in general with regular expressions. Using regular expressions to parse HTML: why not?

Instead use an HTML parser like Html Agility Pack. I don't know if it's available for WP7, though.

The HAP does work with WP7. Get it from source http://htmlagilitypack.codeplex.com/SourceControl/list/changesets – Matt Lacey Mar 01 '12 at 14:47

Complete solution with regex :

string source ="<img src=\"http://MyUrl.JPG.jpg\"";
var reg = new Regex("src=(?:\"|\')?(?<imgSrc>[^>]*[^/].(?:jpg|bmp|gif|png))(?:\"|\')?");
var match=reg.Match(source);
if(match.Success)
{
  var encod = match.Groups["imgSrc"].Value;
}
