JPEG metadata not correctly stored so that Civitai does not recognize it

[antispam2002]

Your question

When generating images in JPEG format, SwarmUI writes the metadata JSON into "Comments" property which can be inspected e.g. with Windows Explorer. When uploading to Civitai, this information is ignored. BUT - if the image is once opened and saved with e.g. MS Paint, with no changes, then Civitai recognizes the prompt and other generation parameters. SwarmUI, however, cannot read the metadata from this file reporting the following error

11:13:34.916 [Warning] Error reading image metadata for file 'C:/SwarmUI/Output/local/raw/2025-04-21/0936XXX105405116.jpg': Newtonsoft.Json.JsonReaderException: Failed to parse JSON `(Invalid Characters Stripped) `: Unexpected character encountered while parsing value: ?. Path '', line 0, position 0.

   at SwarmUI.Utils.ImageMetadataTracker.GetMetadataFor(String file, String root, Boolean starNoFolders) in C:\SwarmUI\src\Utils\ImageMetadataTracker.cs:line 326

The metadata, however, is still there, and looks - at least visually - absolutely intact. Can SwarmUI write the metadata so that it directly can be parsed by Civitai?

It's probably the weird encoding direction thingy -- iirc there's unfortunately no "correct answer" per se for how it should be done. Rather:

• Swarm should be able to read the other ordering properly
• Civitai should be able to as well

So for Swarm reading the reverse order, I'll mark this as a bug to fix - for civitai, you'll have to poke them about it
