Allign Main Slider image to center : I work on small project , and have one little problem that dont know how to resolve myself. I have Image Gallery with many images but want active image, to be showed into center , without change resolution or image width/height ratio. Link from issue [here][1]. Login is user / password . i tryed to manipulate with this CSS:

    .img {
    margin-left: 200px;
    }

but seems to ruin bottom slider. What to do to set main image on center without change image ratio? See image also, where is marked what i want to do.
