Scaling Images Proportionally in CSS with Max-width

Question

Right now, I\'m using max-width to scale images to fit. However, they don\'t scale proportionally. Is there a way to cause this to happen? I\'m open to Javascript/jQuery.

function resizeBackground() {
    var scale=0; 
    var stageWidth=$(window).width(); 
    var newWidth=$("#myPic").width();
    var stageHeight=$(window).height();
    var newHeight=$("#myPic").height();
    if( $(window).width() > $(window).height() )  {
        scale = stageHeight/newHeight;
        scale = stageWidth/newWidth;
    } else {
        scale = stageWidth/newWidth;
        scale = stageHeight/newHeight;
    }
    newWidth = newWidth*scale;
    newHeight = newHeight*scale
    $("#myPic").width(newWidth);
    $("#myPic").height(newHeight);
}
