#eltpics is a collection of photos, based on a weekly theme, taken by ELT teachers, trainers and writers from around the world.
These are, in turn, available free to others in the field of ELT under a CC license to use in their classroom and on their non-commercial materials.
Anyone interested in joining in can tweet an image with the hashtag #eltpics, and it will then be added to the #eltpics Flickr group.
For a more detailed explanation of how to join in, please see this post.
For ideas on how to use some of the photos, visit the eltpics blog.
