# NAME: genimgindex.pl (see earlier simpe imgindex.pl)
# AIM: Given a BASE folder, seek all IMAGE files, and build
# an 'index' table of images, as HTML ...
# Commands: in-folder [-out out-file]
# 2018-08-25 - Included BMP image files...
# 2018-06-01 - Generate HTML5 template
# 20/04/2016 - Add -a to add text under image
# 06/03/2014 - Add -t <num> to set target width, and -b bare table, suitable for printing
#
# *********************************************************************************
# BUT, is really QUITE SPECIALIZED to generate my 'fg' folder 'Image Index' update,
# in that the @excluded_imgs, and %excluded_html are mainly for that folder,
# and the 'links' are to 'index.htm', #top or #end ... and other things, like
# the CSS include, and javascript include ...
# *********************************************************************************
# 22/12/2011 - Do not do a 'table' is just 1 image
# 08/05/2011 - Fix -out file, and fix image paths
# 08/11/2010 - checkout on FSWeekend pics
# 08/12/2008 - externalise im_get_image_size(file_name), adding imgsize.pl requires
# 19/11/2008 - modified to produce say fg/images index
# 27/09/2007 - some features
# $add_dir and $add_siz to ADD a directory and size columns
# and using ImageMagick identify (if installed) to get image dimensions
# 15/03/2008 - add mutiple columns, especially if image constrained to small thumbnail size
