Thinglink allows the sharing of tagged and annotated images (see link by positioning cursor over image). Thinglink works across platform and device allowing users to work from a variety of devices. In an educational setting the opportunity to work from handhelds in contrast to a camera would offer some advantages as students could annotate images as the images were collected.
If you identify yourself as a teacher when signing up for a channel, Thinglink allows you create channels (see instructions). Channels (see example) offer a way to organize images into albums. As you see from the image below images or channels can then be embedded in other outlets (this is an example of an embedded image).
