Zemanta is a browser plug-in for Firefox and IE, and is available as a bookmarklet for Chrome and Safari.
while you write your blog post in Blogger, Zemanta opens up a sidebar next to the Blogger post editor. After you've written a few sentences, Zemanta analyzes the words in your post and suggests images and video that are relevant to your post; with one click, it inserts them into your post. (The Zemanta screenshot from Flickr in this post was inserted with just that one click.)
Zemanta works on all major blogging and email platforms
