Replacing Slider Images

How do I replace the slider images with my images? I am using the CarsWorld theme

Hi!
To add slide you have to press "upload" --> specify the path to the file. After that the path to the file appears in the "Image URL". Complete the remaining fields of the slide, and then click "Add slide".
Besides, you can simply click on the existing slide and change the path to your image,the content and so on.
