This is a simple class that can be used to generate thumbnais from images in the JPEG format.
You can choose how much you want to reduce your imagesize by typing a number between 1 and 101.
If you type for example 2, the thumbnail will be as half as greate as the
original picture.
The class can resize the original image with a scale that can vary between 1 and 100 times smaller.
The generated thumbnail image is outputted directly to the browser, without saving it to a server side file first.
