J-BusinessDirectory - Changing Banner Image on Homepage

I realise this may be a silly question with a simple solution but I have spent an hour trying to discover how to change the default banner image of the skyline. I have looked in all the obvious places such as within the directory search module itself and within the template but cannot find where the banner image should be uploaded. 

Could anybody advise?

Thanks in advance.

Hi,

The background image can be changed from SP Page Builder pages.
All details can be found on template user manual.

Ah, I found it. It was the cog icon in the SP Page Builder. Thanks George.
