Set Background in Plotly panel

Hi!

There´s any possibility to set a background image on the Plotly plugin (Allows a user to superimpose measurement displays ontop of picture), or how can I edit the code to have that feature?

Searching, I found this simple plugin: https://github.com/squiddy/grafana-image-panel
Is there any way to integrate the feature of this plugin (background image) with Plotly?

Thanks! =D
