It would be nice to have more powerful series option nameing.
the user specifies a core name, and the program adds additional series info.
Rename with core name + a numerical or alphabetical sequence, with punctuation options:
wedding_1, wedding_2, or wedding_001, 002, or wedding_a, b, c, aa, ab, , etc,
include file's date into name
e.g., img001.jpg, img002.jpg becomes wedding-2011-03-20a, wedding-2011-03-20b
