25	* This file is included by the picture page to manage picture metadata
26	*
27	Release 2.0.1 fix translation with common.lang.php definition
28	Release 2.0.2 manage 50D
29	Release 2.0.3/4 default 35mm focal length calculation for most common cameras / DSLR
30	All cameras will take benefit from this file, but the Canon at most.
31	If you have a non Canon body and would like to see the MakerNotes, follow the metadata information, e.g. from
32	http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/ and enhance this file!
