Ken,
Without first reading your reply, I figured perhaps the photo was too tall and edited it both for width and height. Still did not get a large option so will leave it as such. I had looked at my AP149 photo which was far larger in height and that has the large option, so was confused by my inability to get the large option. Not knowing that photo width is the determiner, I will keep that in mind for the future. I can't undo my editing to bring back the width this time.
Meanwhile, pilots first visiting SZP can read the airport entry procedures in AOPA Airports 2013/14 version on page 3-17 or earlier year versions, or in other USA Airports Handbooks.
