I have several images of Sydney Harbor. Because I am not confident of the approval process should I even try submitting these images?
Thanks for writing. Based on the know image restriction guidelines linked here: Known image restrictions
"Photos of the named subject are unacceptable for commercial use. Cityscape, skyline, or vista photos may be acceptable if no single building is the primary subject."
The Sydney Opera house can be used in some cityscape images so yes, I would say all but one of those files is worth submitting. The "concrete sails" shot couldn't be accepted since the opera house is the primary focus of the shot.
