If your slides have different dimensions, it will look like it jumping up and down, but that's the downside of a responsive feature. If your slides are same width and height, it will look good.
Thank you so much balihr for this awesome mod. It works perfectly now that I fixed the images. Makes my site look so much more professional now.
