How to add a customised panoramic photo to a bb website

I want to add a panoramic photo to my website. I have currently added it on my webpage, but, as it is so wide, it is hard to view. Ideally, it would be on the site in a way that the user can scroll horizontally to view it rather than see the entire image on the webpage. this would make it taller and easier to view.

Can anyone help with how i might achieve this?
