This is a great tool to use in conjunction with say Google Picasa, Flickr or really any hardware supporting digital photo images. A Image Manipulation website i use frequently is Picnik, it enables you to easily upload photos and play with them in many different ways. Depending on the time you want to spend playing with your shot, there are options for all levels of enthusiast.
Students can incorporate pictures into presentations and manipulate them as they please. Allowing students to develop through their own creativity towards a task can create interest, it lets them develop their own identity. Prensky(2005) believes all students are expecting to be engaged, in their lives outside of school they have friends, games and technologies that supply the engagement, they want to create their own identity.
I think Picnik is a good example of a Image Manipulator. It is fun and relatively easy to use, you can upload shots off many networks, and has easy linkages allowing the export of photographic content to other ICT's. What studentS create in class can then be posted or reviewed by peers or parents in their social networks, providing a sense of ownership towards their creation.
