How to resize multiple images at once

Hi! This post is about a common need for everyone. That's highly probable that, at least once, you needed to resize lots of pictures, either to spare some storage space or just because you needed them to have a specific size for some reason. Below you'll find a script to do it with no effort :) It is based on my previous script for Overlaying a logo in multiple images at once. Once again we'll use the "convert" program from the Imagemagick toolkit.

The world famous Raspberry Pi (model B) has arrived! :) I thought that I would have to wait 1 or 2 months from the order date to get one but happily it only took 2 or 3 days! RS was extremely fast shipping it :)
