This is a text-only version of the following page on https://raymii.org: --- Title : Imagemagick thumbnailer Author : Remy van Elst Date : 29-11-2007 URL : https://raymii.org/s/snippets/Imagemagick-thumbnailer.html Format : Markdown/HTML --- Below you'll find the script that makes nice thumbnails from a bunch of images. I've used it on the links page on this website. (Which is not around anymore). First I made screenshots of the website's I wanted, with the firefox add-on screengrab. It also works with pictures, but then you'll have to change the png to jpg in the script. The script also makes a HTML page with a 2 collumn table witth the thumbs in it.
