Hi Gesi,
There is no such a feature in our Theme and you will need a Custom Javascript code for that. We will do our best to help you on that matter but we will not be able to implement the feature for you.
First, you need to install the Revolution Slider plugin and add a slider which will have all the slides you need to change.
Then please use go to WordPress Dashboard > Pro > Header and add a header and use the Content Area element . Then use the Revolution Slider shortcode to add the slider that you want into the Content Area element.
After that, you can use the Tabs element in the header to add the tab effect that you gave the link to.
That will give you the building block of the needed element that you want to have the effect. After that kindly get back to us to suggest you a Javascript code to implement the functionality.
The idea of the code will be to trigger the NEXT or PREVIOUS SLIDE event whenever you click a tab item.
Thank you.
