requested to merge pabloyoyoista/compose-appstream-generator:media-url into master
Otherwise remote media like remote icons and screenshots are only reference the original origins, having a much worse data quality.
In principle this should have been enough for screenshots to show in GNOME Software. Unfortunately the expected behavior was not documented and a patch is needed in GNOME Software. I will do that in the following days/weeks. But at least once the fix lands in GNOME Software, the appstream data will be of enough quality to display screenshots and remote icons :)
