Converts all images in a directory with a 600px height pattern. Also script makes 120px height thumbnails. Images name pattern 00.jpg, 01.jpg, ... All thubnails will have the same names but with suffix '_s'(00_s.jpg, 01_s.jpg, ... required http://wand-py.org/ Usage: $ python img-to-pattern.py <path>
