Photo Soup is a new service from Yahoo and Flickr (you do not need to have an account to use the service). Photo Soup creates word searches based on images tagged with the subject you provide. Once the word search is generate (it takes only seconds to generate) you can then play the word search online, print the word search, or embed the word search into a web site as I have done below. To create my word search all I did was type in the word Africa then Photo Soup retrieved images and words related to Africa.
Applications For Educators
The word puzzles generated with accompanying images are useful for upper elementary grades through middle school grades. Almost any key word you insert will generate a word search with images.
