I guess you are lokking for something like <canvas>. Firefox and Safari do support it. I am not shure about Opera, but IE and Konqueror don't. For IE there is at least IECanvas (http://sourceforge.net/projects/iecanvas), which might be of use. You can use JavaScript to put an Image on a canvas and you also have drawing primitives to add Information. Christof
