Hi,

I am currently using plotly offline (python 3) but I would like to be able to display images on hover event. There is a solution on Git ([https://github.com/etpinard/plotly-dashboards/tree/master/hover-images](https://github.com/etpinard/plotly-dashboards/tree/master/hover-images)) but I was unable to get this to work offline. The project I am currently working on will not have internet access so I am hoping that there is a solution that would allow me to display images on a plotly graph offline.

Any advice would be greatly appreciated

Thank you in advance  
Mike
