When an image can be magnified there is no cursor change (mouseover change to magnifying glass) to let you know. Though after you magnify an image by clicking on it, there is a minus-magnifying glass to let you know you can click to get back to the initial size.
This seems like an odd oversight. Does anyone know if there's a way in Rise to get this working? (Note - I can do this via css in the index.html after export, but I don't like to do that).
