Let Users Preview Thumbnails with SnapShots

Snap Shots enhance links with visual previews of the destination site, including summaries of Wikipedia and IMDb, YouTube videos, stock charts, RSS feed and more. For website users, it’s an enhanced way to surf because links are no longer blind, they can view the screenshots/thumbnails before clicking on the link. To make Snap Shots feel more integrated into your site, they designed them to be customized with your logo and your choice of color theme and language as well.
