Turn the default "zoom image on click" off for accessibility

I just attended an NVDA training and was fortunate to be able to have part of a RISE course of mine tested.  I had an image that I left the alt text as blank (to mark as decorative) but through the test even though the image was decorative, I had left the zoom image on click check box turned on (defaults on) not realizing a screen reader will still read this because it is an interactive element, even though the image itself is decorative. 

I struggle with this logic, however, on this note, could Articulate uncheck the zoom image on click as the default setting?  This way if you actually want your learners to have the option to zoom you have to consciously think about adding it.  Where as most times the zoom is not necessary and vey confusing if a designer forgets and the person using the screen reader gets the frustration.

I am hoping this may be a "quick win" for Articulate to aid us on being more aware of accessibility needs.  I am sure many of us have a decorative image with the zoom on.

Thanks for reading
