@antp, when giving a hand with https://www.imcdb.org/vehicle.php?id=122801#Comment3187692 I stumbled upon a case of the old picture being kept in my local cache. In the process I may have ended up offending dhill_cb7....

Refreshing the page, even opening in a new tab, did nothing. Clearing a cache of 1GB solved the issue, but is this a known issue?
