If the image widget takes up the whole width of a dashboard, when viewing with a mobile device scrolling with one finger will not occur when swiping over the image widget. Instead it moves and un-zoomed image around with your movements making scrolling difficult. The image widget does not respect the outer boundaries of the image it is displaying and moves no matter what. You must grab an edge or border between widgets in order to perform the scrolling action. This is a huge problem for me on all my dashboards when viewed for mobile.

I would like to propose that scrolling and zooming in an image should only happen with two fingers. 

Please :)
