    Question getting mouse coords onclick relative to image

    Hi there,

    I am trying to create a javascript that will return the coords of where the mouse clicked on an image. I know there are script that will do this sort of thing but they always return the value relative to the whole document (top left of browser screen is 0,0) i would like the coordinates relative to the image (topleft of image is 0,0)

    Can anyone help??

     if (typeof zxce.layerX=='undefined') zxce.layerX=zxce.offsetX;
     if (typeof zxce.layerY=='undefined') zxce.layerY=zxce.offsetY;
     alert('Left: '+zxce.layerX+'\nTop: '+zxce.layerY);
     return [zxce.layerX,zxce.layerY];
