Snap.com

Writing about web page http://snap.com

This is clever. It's a search engine which provides a screenshot of each result when you select it. I wonder how it's done? Presumably at the same time as they request the page to index it they also have a system for saving an image of the page.

It's clearly not fetching the image at the time you perform the search, because a search which returns my blog includes a screenshot showing it as it was on Sunday 9th April. So the images are generated when the indexing takes place. But how, I wonder? Is there a trick which allows for programmatically saving the visible portion of the browser window as an image file?
