You can only see the images of the generation you are asked to give an echo.
As a reminder, there must be an association of ideas between your picture and the one you choose to answer.
You can’t see what the other participants have posted.
You click on the picture you want to give an echo to post your image.
If you refresh the page, pictures will appear in a different order (this is for the “shuffle” part!).
If there is no image left on this page, that means that all the echoes have already been posted.
You will find here the possible echoes.
