Many Flickr users have chosen to offer their work under a Creative Commons License, and you can browse or search through content under each of the types of licenses. This means that Flickr is a great place to find images to illustrate your handouts online worksheets or presentations. It also means that students can obtain images for their own presentations or assignment without breaching copyright.
Flickr also has the ability to Geo-Tag images. This means that images have the geographical location embedded into the digital information that is recorded with the image. You can locate where the image was taken on a google map or google satellite image.
