Custom width and height on fancybox image

Question

I wonder if it is posible to set a custom width and height on fancybox images?

As a standard, the width and height of the fancybox changes in relative to the width a

Answer 1

A simpler way is to change the size of both, the fancybox opened image AND the fancybox parent container using the beforeShow callback like :

$(".fancybox").fancybox({
    fitToView: false, // avoids scaling the image to fit in the viewport
    beforeShow: function () {
        // set size to (fancybox) img
        $(".fancybox-image").css({
            "width": 800,
            "height": 600
        });
        // set size for parent container
        this.width = 800;
        this.height = 600;
    }
});

NOTE : this is for fancybox v2.x+

EDIT (April 2014) :

With the current version of fancybox (v2.1.5 as today), it's not necessary to apply css rules to the .fancybox-image selector since images are now set to be responsive (max-width: 100%;). this.width and this.height alone will do the trick

$(".fancybox").fancybox({
    fitToView: false,
    beforeShow: function () {
        this.width = 800;
        this.height = 600;
    }
});
