<<The quality is fantastic, there is a well known web database of 'Airliners' you should get them uploaded.>>
I know from bitter experience that few would make it onto the major sites. They look for a) technical excellence, i.e focus, levels, etc., b) aircraft must be centred on the frame and c) they must be level, i.e. the surrounding terrain must be horizontal or any buildings must be perpendicular. However, a few minutes with Photoshop would sort them out..
If he levels them and slightly adjust the contrast, Air Britain pics is more concerned with the aeronautical content that photographic excellence so they would get in there probably.
Lastly, Fotopic provides free photo albums so that everyone can access them on line. Might be an idea to upload them there...
