Looking for a simple image zoom/pan plugin

I’m looking for a free plugin like this one: https://codecanyon.net/item/image-zoom-pan-wordpress-plugin/6133914

I just can’t afford the $70 price tag that goes along with this plugin.
Anything that’s nice and simple like the plugin above will work for me. I’ve been trying to find something all day that will work for the site I’m working on however I’m having no luck.

Thank you.
