Hello johnnyb50uk,
Thank you for interest in our theme Corporate Plus Pro.
In free theme only text slider available but in the pro theme images + text sliders added which means you can have multiple slider images.
Also for the inner header images, the header image of the customizer will be used.
You can see that in our demo too:
