2. Kwout
   
   Kwout is a free service that you can use to cut out parts of web pages and embed them elsewhere. It is really easy to use, as you just have to add a bookmarklet to start using it: when you are on a web page, just click it, and a new window will display a picture of the page you were browsing. Select the area you wish to cut out, refine it with borders and shadows, and get the embedding code. You can also upload it directly to your Flickr or Tumblr account. Free.
