title: Take screenshot with Selenium: WaitForPageToLoad does not wait long enough
body: <p>I'm trying to get screenshots from a web page with multiple browsers. Just experimenting with Selenium RC, I wrote code like this:</p>
  
  <pre><code>var sel = new DefaultSelenium(server, 4444, target, url);
  sel.Start();
  sel.Open(url);
  sel.WaitForPageToLoad("30000");
  var imageString = sel.CaptureScreenshotToString();
  </code></pre>
  
  <p>This basically works, but in most cases the screenshot is of a blank browser window, because the page is not yet ready for display. It kind of works if I add a sleep just after the WaitForPageToLoad, but that slows down the fast browsers and/or may be to short for the slower browsers (or under load).</p>
  
  <p>A typical solution for this seems to be to wait for the presence of a certain element. However, this is meant as a simple generic solution to get a screenshot of a local web page with as many browsers as possible (to test the layout) and I don't want to have to enter certain element names or whatever. It's a simple tool where you just enter the Selenium Server URL and the URL you want to test, and get the screenshots back.</p>
  
  <p>Any advice?</p>
