The problem is that you're hiding the list-items that contain your images in your website. Have a look below,
.rslides li {
-webkit-backface-visibility: hidden;
position: absolute;
display: none;
width: 100%;
left: 0;
top: 0;
}
Which is then applied to the images (or any other child element) inside this list-item. Try removing this, and then reload the web page. This time, the display would not be none and your images will be displayed.
Tip: Try using block
instead of none.
