Use Smartphones instead of Cameras in Primaries
How's about using cheap (<£100 smartphones) instead of cameras in class?
They come with cameras and wi-fi and apps to do things with the pictures. :)
The pics can be uploaded direct to a school twitter account for show and tell (v easy to help maintain a dynamic website :) )
Or just uploaded to a school dropbox account (dropbox priviacy issues permitting :) )
Or just have a simple SMB app to just copy and paste them to the school server.
And then because you've got a "smart" device - it can be used for other applications/ideas as well
