Can I have a little thumbnail next to my posts - like boxes?

[bizint 0]

For "boxes" you can upload an image for a small thumbnail...but for the posts, I cant seem to have a small thumbnail next too those....can this be done? Ignore my layout...but boxes at the bottom, called manage connections etc... have small thumbnail to side..or middle above...etc....but the posts listed under "latest news" in the right cant have a thumbnail? or can they>? http://www.businessinteriors.co.uk/betatest/wordpress/case-studies

You'll want a plugin to get a thumbnailed widget like that.
