Is the image actually broken or do you just get a message that it is?

302 implies that the image already exists... maybe the same image is on multiple work items.

I think this issue can be closed. HTTP 302 is a redirection and automatic follow of redirection was disabled in this tool. This was fixed on 24.9.2025 in commit 2d2b6a7.
