Hi John,

In version 2.0 of the framework there are actually only two images.  Also, the authoring tool does have an 'Autofill' option on the way very soon, which can set a selected image to be used in all graphic sources.

During development we had discussed potentially cropping or allowing the user to select different parts of a larger image for different viewports, but a decision was taken that allowing different mages provides more flexibility for mobile/tablets.  

Regards,

Brian
