Wanna make /everybody/ happy?  Impossible, but this comes close:

Mirror the image on archive.org.

1)  Put your image - any size - on any web server.

2)  Go to archive.org, and enter its URL in the Wayback Machine.

3)  Click the link provided to /add/ your image to the Archive.

4)  Copy the resulting URL and viola, durable offsite hosting.

https://web.archive.org/web/20180315211057/http://pilobilus.net/Fat.Freddy.Sez.jpg

To prevent the resulting longish URL from 'breaking' when wrapped,
clearsigned, quoted, etc. (and annoy one or two list subscribers)
shorten the URL:

https://tinyurl.com/y8vscppm

Include a hash for your image in your clearsigned post and viola,
authentication / non-repudiation and two defensible 3rd party time
stamps (list server, archive.org) in one compact package.  Example:

SHA256:
6456d5de64fb828d215cdcc6976d0d85fb95501fcc21444488519461ce98d5cc

:o)
