Am thinking of experimenting with images.
I like the idea of getting a custom "Piece in process" image... sort like https://i.imgur.com/removed.png but with an appropriate Pieces message that changes as backing takes place with the image becoming the actual image upon successful unlock.
eg: https://trypieces.com/u/john/i/i493493295.png
This would work anywhere across the web that allows for image deep-linking. (not 4chan)
You could run a text-to-image function if the Piece is textual to generate such images. eg
https://pbs.twimg.com/media/HJgAcAaXcAM_49r?format=jpg&name=...
But, hosting the images is the major issue here. Perhaps create a Wordpress plugin that integrates with Pieces? Provide an API?
But even if it can't convert to the actual image, it's still a good idea for marketing. It could say something like. "Image unlocked, see ____.com [custom domain] or trypieces.com/____ for the full reveal" or just "released through TryPieces"
