Remove Pictures Behind The Slide

Hello I am going to be buying this tomorrow but I need to know how to change or remove the pictures behind the slider? I don't see them in the control panel. Great theme..

Hi!
Could you clarify which images you would like to remove?

You must go to Cpanel on your hosting, download that picture (slider.png), edit it and upload in the same folder. Don't change file name (slider.png)
