Raymii.org

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.

Recently I removed all Google Ads from this site due to their invasive tracking, as well as Google Analytics. Please, if you found this content useful, consider a small donation using any of the options below:

The thumbing effect was copied from the example pages from imagemagick.
