afaik, if you have corner coordinates of the photo, they have to be in some projection already. If the are in lon/lat, you can use openlayers default projection epsg:4326 (WGS84). I would use single file, for the image display. it is imho the easiest way, how to put some data on the screen. jachym -- Jachym Cepicky e-mail: jachym.cepicky gmail com URL: http://les-ejk.cz GPG: http://www.les-ejk.cz/pgp/jachym_cepicky-gpg.pub
