Hello. I have just joined airliners.net and would like to submit photos. Can someone inform me of where I can find the parameters for airliners.net to accept photos? Thank in advance, Bob.
Welcome to Airliners.net. The best place to start would be to review the Acceptance Guide located on the photo upload page. You can also find it here: https://www.airliners.net/faq/photo_acceptance_guide/ The document is somewhat dated, but the acceptance criteria still apply.
Also feel free to discuss images before submission on the Photography Feedback Forum where other photographers and screeners participate and provide feedback.
