if you are using http://del.icio.us then i recommend you also try http://thumblicio.us.

thumblicious provides you with screenshots using thumbnail from cached snapshots for the bookmarks tagged at del.icio.us.

the screenshots are powered by another site thumbshots.com who are the leaders of web preview technologies.

it is a great handy side when you would like to preview the websites before loading them while doing a tag search at del.icio.us, this site directly plugs into delicious to show you screenshots of websites.

overall its a very cool site and is rather a big help to those who want to view previews before actually visiting the sites, its also a time saver naturally.
