[ Plugin: RoyalSlider ] How to have slider "randomize' order of my images on dis

Hey I am looking for some way to randomize the images in my homepage slideshow. I contact the developer asking for direction or help and it wasn’t much help. I only am using two slider and preferably would like to make one (homepage slider) randomize the images but if I have to make both random then I can live with that. Any suggestions on how to do this? The site is Murrayconstructionco.com and the slider I am talking about is on the homepage (not gallery page) Thanks
