Original GitHub issue: https://github.com/binwiederhier/ntfy/issues/1436

Either via ntfy.sh or self-hosting, I find that the 'Icon' header no longer seems to be working for me, using the ntfy web client.

E.g.

user@host:~$ curl --header 'Icon: https://upload.wikimedia.org/wikipedia/commons/b/b5/Green_icon_-_Settings.ZGH.png' -d "Test"  https://ntfy.sh/github-issue-icon-header

Gives this response:

{"id":"cCK7TPfnlBPt","time":1756196408,"expires":1756239608,"event":"message","topic":"github-issue-icon-header","message":"Test","icon":"https://upload.wikimedia.org/wikipedia/commons/b/b5/Green_icon_-_Settings.ZGH.png"}

However, in the web client, I see this:

I've tried this in different browsers, with the same result.

Is this a bug or am I misusing the feature?

PS, I don't see any CORS warnings in browser console, but this seems the most likely issue?
The NTFY documentation was a little lacking in this area about Icons

Icons are only supported on the Android app right now, not on the web app

Ah, my apologies. I was looking for this information, but somehow missed it.

I am wondering if this makes sense to add to the web app as a feature?! CORS may almost certainly render this feature unusable in most cases, right?
