workflow should be embedded into the picture
Unfortunately, I think lemmy strips the metadata as a safety precaution so people don't accidentally share their GPS coordinates when posting photos from their phones. A third party file sharing host is often used for sharing images with workflows intact, such as Google Drive, Catbox, etc.
I'm guessing there is a problem with federation to lemmy.world. Another user from that instance is having the same problem. Check the home instance of this community at https://sh.itjust.works/c/imageai. It also shows as pinned on the sopuli.xyz instance.
