Question

Is there any way to set a fixed/custom height for ligtbox2?

#lightbox img{ width: auto; height: 600px;}   

This only resizes the img and not the outer container.

None of these solutions worked, but thanks for your help guys. I had to get my hands dirty in the js… here’s my hacked code:
lightbox.js

...
     // once image is preloaded, resize image container


            imgPreloader.onload = (function(){
                var scale = 600 / imgPreloader.height; //modified
                this.lightboxImage.src = this.imageArray[this.activeImage][0];
                this.resizeImageContainer((imgPreloader.width * scale), //modified imgPreloader.height);
            }).bind(this);
            imgPreloader.src = this.imageArray[this.activeImage][0];
        },

        //
        //  resizeImageContainer()
        //
        resizeImageContainer: function(imgWidth, imgHeight) {

            // get current width and height
            var widthCurrent  = this.outerImageContainer.getWidth();
            var heightCurrent = this.outerImageContainer.getHeight();

            // get new width and height

            var widthNew  = (imgWidth + LightboxOptions.borderSize * 2);
            var heightNew = (600 + LightboxOptions.borderSize * 2); //modified
