Google Instant Previews - No Flash?

You've probably seen Google Instant Previews on your searches. These show up when you click the magnifying glass next to a search result and show you a preview of where the link will take you. According to Google, 1 in 20 searchers are more likely to be satisified with the results they click.

However, it seems that it doesn't display Flash or Silverlight content. This means that websites that don't provide an alternate image for browsers that don't have the plugin installed don't get a preview.

This is another reason why your website developer should provide alternatives to any elements that require third-party plugins.
