Hi, my image is 2000x1000px. I need it to be full screen when it opens. (full size) and that is the minimum zoom. Which values should i adjust?
And last, is there a way to make it responsive? (that is shrinks proportionally depending on the screen size).
Sorry for so many questions and thanks a lot for your time.
