Jssor Images Too Zoomed In

Question 1

Just added a max-width and max-height to my CSS, like this:

<style>
#slider1_container img {
    max-width:100%;
    max-height:100%;
}
</style>

Question 2

There is an option for FillMode which is 5. That says (contain for large image, actual size for small image). Haven't tried it but it should work.

        var jssor_slider1 = new $JssorSlider$('slider1_container', options);

        //responsive code begin
        //you can remove responsive code if you don't want the slider scales
        //while window resizes
        function ScaleSlider() {
            var parentWidth = $('#slider1_container').parent().width();
            if (parentWidth) {
                jssor_slider1.$ScaleWidth(parentWidth);
            }
            else
                window.setTimeout(ScaleSlider, 30);
        }
        //Scale slider after document ready
        ScaleSlider();
        $(window).bind("load", ScaleSlider);
        $(window).bind("resize", ScaleSlider);
        $(window).bind("orientationchange", ScaleSlider);
        //responsive code end
    });

</body>
</html>

Question 4

Have the very same problem a couple of years later. Don't really want to hack around with css, I assume it must be a bug in either how $FillMode works, OR there must be some non-obvious container/conflict with it. Definitely never 'contain's images, tried all $FillMode s
