We are now trying out image grids where rather than words you guess based on images. Due to the increased potential for abuse, for the moment we are only allowing Patreon backers, to submit these.
If you are a signed in Patreon backer (you are not at the moment, if you have backed us then sign in ) then go to the submit page but instead of entering words as the members of the groups enter the URLs of images. Images should be in landscape orientation so they fit.
We do not host images, they must be hosted elsewhere. You could try uploading your own images to a service like catbox.
