Creating thumbnails in linux is relatively with a few open source tools. I wrote these programs and use them for all of the images that you see on this website. They're really useful for modifying large batches and scaling correctly. You'll need the following installed on your machine:
  • Linux
  • PERL
  • image magick
  • Image::Magick
Create Thumbnails - if you pass a -w <width> it will attempt to scale the image down to that width for you. Default is 500 pixels.
Create a html page of the thumbnails you just produced.
