# the file has been heavily modified by myself

thumbnail_multipage -- generate W3 compliant html pages with thumbnails to click on for a number of images.
USAGE: htmlthumbnails [-h] [ -W width] [-H height] [-N name_of_html_page] [-n number_of_image_per_page] path/image1 image2 ...
OPTIONS: -h this help.
EXAMPLE: htmlthumbnails -W 120 -H 80 -N page -n 6 image1 image2
EXAMPLE: htmlthumbnails -W 80 -H 120 -N page -n 6 ~/images/*.jpeg
The html code is written to files called name_of_html_page_file_number.html.
I recommend leaving the script always in the same folder and using the absolute path for the images (~/path/image).
All thumbnails have a size of widthxheight.
Make sure you use the right orientation.

This script requires ImageMagick

if you modify the script, make sure the html file still validates as HTML 4.01 Transitional!
