#!/bin/sh ## ## SCRIPT: htm00_multi-img-files_thumb-TableCELLS_NperRow_links2originals_echo_for-loop.sh ## ## PURPOSE: Generate an HTML file showing thumbnails of image files IN ROWS ## down the page --- in table rows, N cells per row --- ## using the selected image files ('.jpg', '.gif' or whatever). ## ## METHOD: Uses 'zenity --entry' to prompt for N (the number of cells per row). ## ## Uses 'echo' to build the HTML file. ## ## This script shows the HTML file in an html-viewer of the user's choice ## ($HTMLVIEWER), and puts the user in edit mode on the HTML file ## using a text-editor of the user's choice ($TEXTEDITOR). ## ## HOW TO USE: In Nautilus, select one or more image files in a directory. ## Then right-click and select this script to run (name above). ## ## It is assumed that you have created a subdirectory called ## 'thumbs' in that directory, in which the thumbnail files ## exist and are JPEG files with names with suffixes '_thumb.jpg'. ## ## Examples: ## yada_yada_yada_666x488.jpg ## has thumbnail file ## ./thumbs/yada_yada_yada_666x488_thumb.jpg ## ## and/or (if the original is a GIF file) ## yada_yada_yada_666x488.gif ## has thumbnail file ## ./thumbs/yada_yada_yada_666x488_thumb.jpg ## ############################################################################## ## Started: 2009aug18 ## Updated: 2010jul20 ## Updated: 2011apr12 Converted to a Nautilus script, to gather selected files ## via Nautilus navigation and selection. ## Changed: 2011may11 Get 'nautilus-scripts' directory via an include script. ## Changed: 2011jul07 Changed to handle filenames with embedded spaces. ## (Removed use of FILENAMES var and use a 'for' loop ## WITHOUT the 'in' phrase.
