Hi Godwit...
The 'Chain' is a forum in which you post pictures which have a link to the picture posted previously; for example, if you wanted to add an image you could post a picture of a bridge, water, stone, sunshine, a Duke or whatever as long as it has a link, however tenuous, to the picture posted by Ertrum.
Whoever posts after you would then take an element from your image.
Have a go!
