Image resize to fit screen

Question

I created this code to resize photos/images to fit the screen, considering the space available for the nav bar.

The script fires on image load and on navigation clic

Answer 1

I wrote a plugin!

jQuery.fn.positionMe = function () {
    var oH = $(window).height();
    var oW = $(window).width();
    var iH = this.outerHeight();
    var iW = this.outerWidth();

    // When the image is too small so, do nothing
    if(iW>oW && iH>oH){

        // Otherwise, proportionate the image relative 
        // to its container
        if(oH/iH > oW/iW){
            this.css("width", oW);
            this.css("height", iH*(oW/iW))
        } else {
            this.css("height", oH);
            this.css("width", iW*(oH/iH));
        }

    }
    return this;
}

Usage:

$("#photo").positionMe();
