With the recent redesign of delicious.com, they've added a much more graphical home page. The site continues to be a service for people to bookmark and share websites they come across on the web. The delicious home is now made up of images taken from those linked sites. See for yourself at http://delicious.com
I would like to know what in the law allows them to do this, considering the images represent the main content of the page, and they clearly do not own copyright to those images? I know there is some leeway given to search engines where it is considered fair use to use a small portion of the content if the aim is to lead people to the originating site. Does that apply here?
