Issues and comments take text only; a bug report with a screenshot means hosting the image elsewhere. Forgejo has attachments, sourcehut does not. Release assets already stream to disk and back over SSH, so the storage and the serving path exist.
Ref #185
I'm going to opt not to implement this feature at this time. If we need to add images or files, let's use external file sharing hosts instead and paste the links in here. Can be reopened at a later date if we find this is a real blocker in our work streams.
