When you think a RegExp might solve your problem - stop for a moment
and think whether there is also a simpler solution :)

In this case, I'd just do:

  function name(url) {
    var name_end = url.lastIndexOf(".");
    var name_start = url.lastIndexOf("/", name_end) + 1;
    return url.substr(name_start, name_end);
  }

If your URLs aren't always that simple, you'd need to adapt a RegExp too.
