How to set Full Width Image on Pages

Hi guys,

I am using Flatsome theme for my blog and I want to set the image on the top of each page to display in full length. I have a right sidebar and somehow can't figure out what to do to make the image appear in full length above the content and the sidebar. It always appears above the contents but next to the sidebar.

Can anyone advise what needs to be done to have the image displayed in full length above the contents and the sidebar?
Thanks

you need "per page" customization options. If the theme doesn't offer you the ability to choose layouts for each page individually I don't think you can do this. So, toy with the theme options some more, and check out the page options in particular
