Linking N-numbers to Charter Flight numbers (for photos)

I know that FA has some software logic that ties an executive charter company’s flight numbers to the corresponding N-number so that the correct aircraft’s photo will be shown when the flight is tracked.

For whatever reason, the following flight operated by Chantilly Air is showing up with no photo, yet the aircraft has 4 photos in the database.

Should the photos be re-uploaded with Chantilly’s flight number in place of the N-number?

Flight: flightaware.com/live/flight/WML5 … /KFDK/KHEF

Aircraft: flightaware.com/photos/aircraft/N534NA

The aircraft is flying under the call sign WML54. You may need to add “WML” to the airline field. This is located in the upload area labeled “Photo Tags.”

Tried that, and the photo-tag auto-complete program does not recognize WML as a valid airline.

I have dozens of other photos uploaded that match correctly through whatever method FA is using to tie them together. This one aircraft is (for me) an exception.
