Classroom displays by teachers around the world are now commonplace on the web. For example, go to the http://lmhartley.edublogs.org/ and you will find detailed examples of work displayed by teachers. Some of them have linked their pages to Flickr (www.flickr.com), which is a free photo uploading service that allows you to share comments on pictures.
