Took some trial and error to set up, but i found an extensive dialogue and help section on the developer's site - better than on wordpress support page. It solved my main problem of image being cut off - TURN OF "CENTER" option when choosing full screen.
Because this does such specific things, it requires a little set-up. But the developer has tried to make it easy using little flag prompts to get you headed in right direction .EXCELLENT user interface and fore thought. Very pro plug in. Toss the guy some cash if you use it. I tried doing this kind of thing on my own and it twisted my brain.
