This video is an introduction to images, whether they are
photos, diagrams, drawings, paintings, scans or other pictures.
We add a photo to a blog post and also mention the use of other
people's images that have been released under a Creative Commons
licence. One place to find these is by searching Flickr, the photo
sharing website.
Incidentally, you can license your own work
under a Creative Commons licence, whether that be photos, video or
text. There are many reasons why
you might wish to do so.
