One of the Web tools I put on the list was Photovisi. Photovisi allows you to easily create eye-catching photo collages by using your own photos stored on your computer.
You can use a variety of funky templates so that very few poster ever look the same. Once you choose one of templates you simply add as many photos the template allows.
Instructions to students are very simple: Upload the pictures, move and rotate them to modify the template and create your own collage with your own photos.
Once you'll have finished your masterpiece, Photovisi allows you to save it in many different formats and resolutions. It would be perfect to then combine this with another Web 2.0 tool and print these out using Block Poster (previewed previously) a tool that allows you to print out an image to any size.
