Jquery click image to rotate:

var angle = 90;
$('#rightwayup').on("click", function() {
    $(this).css({
        '-webkit-transform': 'rotate(' + angle + 'deg)',
            '-moz-transform': 'rotate(' + angle + 'deg)',
            '-o-transform': 'rotate(' + angle + 'deg)',
            '-ms-transform': 'rotate(' + angle + 'deg)'
    });
    angle += 90;
});

<img id="rightwayup" src="http://i.imgur.com/3nTTzTd.png" alt="" />

#rightwayup {
position:fixed;
-webkit-transition: all .5s ease-out;
   -moz-transition: all .5s ease-out;
    -ms-transition: all .5s ease-out;
     -o-transition: all .5s ease-out;
        transition: all .5s ease-out;
}

Not tested in vbulletin and probably conflicts with something like prev/next but hey its just my 2 cents,
