GitHub Issues: Image upload

GitHub Issues: Image upload

For a few days I have had problems with the image upload in GitHub issues.

1a) New comment: The upload dialog does not open.

1b) Editing an existing comment: Images are uploaded, but are not displayed as an image. Only the link to upload is shown instead.

2a) Embedded images in emails are not transmitted. Instead, a text placeholder is displayed. It is probably the metadata of the upload from the email client.

2b) Attached images in emails are ignored.

Does the transmission of images by email generally work?

The error does not occur all the time.
