ImageMagick thumbnailer scripts for blog

Hey there, I’d like to share my dirt-easy script for creating thumbnail in blog post. The script will scale any image to the width of 456pixels which I find acceptable by most blog theme (actually the limit is around 460-465 pixel, but better be safe).

Why I wrote yet another script for scaling images? because I find blogger.com and WordPress system of uploading images and photo annoys me, and I rather upload my pictures/photos on my own private server and create thumbnails on my own.

I licensed the download under WTFPL , don’t worry its a free software license.
