- fix inconsistent way to refer to ImageMagick binary (parameter ImageMagickPath vs. image::identify_binary) - fix incorrect way to refer to results of ImageMagick (foreach was dangerous and incorrect) - fix incorrect parameter to ImageMagick (-size geometry) - fix broken switch statement - fix typo in name (image::imagmagick_identify should be imagemagick_identify) - fix incorrect comments - provide default to optional argument of filename_mime_type - try to use built-in support and fall back to external programs (image magick). Built-in support is several hundred times faster. - use NaviServer's extened functionality
