Correct graphics resizing poster

A simple colourful poster to remind students the correct way to resize graphics so that they remain in proportion when they make an image smaller. It also reminds them that images can only be resized smaller - making an image larger will cause pixellation. Poorly resized images that are stretched out of proportion drive many teachers to distraction - perhaps this will help? Please note that many applications require a key such as shift to be used in conjunction with the corner handles. Most, but not all, use shift so I have let this off the poster.
