Under My Tools in the left menu, and below the Sliders, select Circular Slider to navigate to a page containing a list of your circular sliders or create a new one. When the slider setting page is opened, like other tools, please choose a desired name for your slider. After that, you have to fill two other inputs. The first input is a place to paste the desired sliders images. And the second one is for defining delay between the slides.
Simply see the preview and copy the code and use it wherever you like.
