Image control

Alyssa, thank you for this workaround. I was having the same problem as Martin and could not figure out what to do. For anyone else who stumbles on this thread, here is a summary of the issue I had:

1. I wanted to display a full-width image which would scale with the screen size without getting cropped.
2. I learned that when using the "Image Full Width" block type, Rise automatically crops the image rather than just scaling it. This is problematic if you want the learner to be able to see the entire image. Using this block type, there is no way to predict how much of the image the learner will actually see. 
3. I learned (in this thread) that using the interactive "Labeled Graphic" block type -- then changing the setting to "full width" -- forces Rise to display the entire image. Using this block type, Rise will scale the full-width image with the screen size rather than cropping the image to fit the screen. 

This is a really helpful tip (which may be subject to change in the future if Rise updates the "Image Full Width" block type to allow scaling rather than auto-cropping).
