| 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. |
