[Plugin: Shadowbox JS] help with navigation – next/previous

i tried all all the JS libraries and i don’t know what the difference is. Shadowbox JS seems to work fine, but navigating from one image to the next is not very intuitive – you have to click the little >>, whereas in may others you only need to click the image, or click the right/left half of the image to move forward/back

can this be shanged in Shadowbox JS?
