360 degrees panoramas can be marked with the {{Pano360}} template, which enables specific features.
Example usage: https://commons.wikimedia.org/w/index.php?title=File:Binsfeldsee_Panorama.jpg&action=edit
When the description contains the string "360", we could:
- Ask the uploader
Is this picture a 360 degrees panorama? with answers Yes and No
- If yes, add
{{Pano360}} after the description
Low priority as the wikis do not currently use that many 360 panoramas-specific features (most are used like normal pictures).
