How do I get the picture to show accross the screen

I am new to wordpress and have decided to use the Dazzling theme.

All good until I want to show the picture across the screen that is in the screenshot of the theme.
This is the picture that comes directly below the menu bar and above the posts and sideboxes.

Can someone please tell me how to get a picture to display there please.

Hi Johanne,

I hope you are well today and thank you for your question.

I think you want to display the Dazzling theme slider on your site which you can configure to display on the following path in the admin area of your site.

Admin Area -> Appearance -> Customize -> Dazzling Options -> Slider options

On the above path to enable slider tick checkbox “Check if you want to enable slider” and you will see the two options will appear called “Slider Category” and “Number of slider items”
Select category from dropdown to use for slider
Now select number of slides to be used in slider (newest Posts from that category will be used)
Make sure you have Featured Images selected for those Posts.

Best Regards,
