Best method to make image readable on mobile

Hi there,

my site has an image of a GIS map that is difficult to read on mobile. What’s the best way to improve this user experience? I was thinking having the image expand on-click within the current view so user can scroll and zoom into the image. I think that’s better than forcing a click to the image URL or leading to something like a custom Google map of the same map. Can anyone recommend ways to implement this within Beaver Builder?
