#! /bin/sh # # Here is a script for making thumbnails and an index.html file # for a directory of jpegs. # # It expects to see a bunch of .jpg or .JPG files in the current # working directory. It chmod 644's all of them, moves all the # .JPG files to .jpg if it doesn't cause a conflict, creates thumbnails # for all of the images, and emits a simple HTML file to easily # browse the images. # For best results, you'll have images with names like # "jason-before-the-game.jpg" (underbars are treated the same). # The resulting HTML file will have a name like "jason before the game" # displayed under the thumbnail. # The thumbnail filenames are based on the image filename. If an image # is called foo.jpg, the thumbnail is foo-t.jpg. # You can adjust the size of the thumbnails with the MAXTHUMBWIDTH and # MAXTHUMBHEIGHT variables down below. # You can adjust the number of columns by changing COLUMNS. # If there is no index.html file present, this script creates one. # If there is an index.html file already, this script sends tthe # HTML it wants to create to stdout. # If you want to leave images out of the HTML index, list them in # a file called DONTSHOW.txt (list the full filenames). They will be # ignored by this script then. # RCS ID: $Id: makethumbs.sh,v 1.5 1998/09/21 07:59:25 molenda Exp $ #---------------------------------------------------------------------- # Written by Jason Molenda, jason-mt@molenda.com, 1998-09-13.
