The problem:
I want to share a unique image each time a url is shared on Facebook. This to let users of my site share emotions and their score from having played the game they just played on the site.
So, they would share the game url, which is the same to all, but associate it with their results and an emoticon or something like that, all baked into an image created on the fly, saved on my server.
I do not want to have to keep those images after they have been shared as storage becomes cluttered.
Is this possible?
AFAIK, sharing a unique image for a url that has been shared many times before can easily be achieved via sending in the img url explicitly to the share.php along with the url to share. Is this a correct assumption?
So the question, as it stands:
Is it possible to share a unique image to the same URL over and over, and then throw away the image but it stays visible with the link on Facebook?
