Images are included in a HTML page via the img tag. This tag supports
defining the width and height of an image. If these informations are given the
browser has not to load the image to know its size and can start rendering the
page earlier. If the browser knows all the geometries of all images of an page,
the rendering of the side becomes much faster.
But it's laboriously to detect all the sizes of all the images. As the result
Leo<HTML>
supports the image tag. It detects itself the geometry
of an image. Therefore it only requieres access to the original image.
