Change header image Joomla 3.6.0

Muhammad: 5 days ago

A friend of mine asked, if I can help him in changing the header image of his Joomla Page. Since I should know how to do this in any CMS, I asked him to provide me with the credentials. However, I did not find the correct menu where I could change the header image.

I also looked up tutorials on the internet on how to do this, such as, this one ( According to this guide, I should go to Extensions => Modules in the admin menu and then look for Images. But I do not see Images in the admin menu of my friend's page. What is wrong? The used version is Joomla! 3.6.0.

Here is a screenshot of the Modules page:

Assuming that by "header image" you are NOT reffering to "Kiperowil" logo in header, but to trucks images in slider underneath, you can change them in 'Vinaora Nivo Slider' published in position-4.
I have seen hundreds of slide-show extensions, but this one is new to me.
