I just sent a Dmail with a picture attached. In the Dmail preview, the right side of the picture was cut off. It also looks cut off when the Dmail is actually sent. However, when I clicked on the cut-off looking picture in the sent Dmail to enlarge it, the entire picture was visible in the enlargement. I have never seen it do this before and I haven't changed any of my settings (that I know of).
This is how the picture looks in the Dmail preview and the body of the Dmail after it is sent:
