Many AI image generators, including the big UIs for Stable Diffusion, helpfully embed metadata in the images so that you can load them up again and get all the settings you need to regenerate the image.
But Lemmy’s built-in pict-rs image hoster, and most image hosters that resize or re-encode images or that try and stop people from doxing themselves with photos’ embedded GPS coordinates, will remove all the metadata. This is counter-productive for AI image generation, because part of the point of sharing the images is so other people can build on the prompts.
What are some good places to host images that don’t strip metadata?
Ipfs stores raw files. You can then use an ipfs relay to get an https link to your image to put it in a post. If you disable pinning, the image might get lost as hosters will stop supporting it if nobody ever accesses it, but imo that’s a feature.
