The effect that shifts the rest of the page up and down depending on the height/type of the slide is very cool. However, in my case I want to shut that off (so that the page content below doesn't shift up and down). So far, I managed to set the image height for portrait (left or right side slides) to match full width images by editing functions.php on line 27 like so:
$avia_config['imgSize']['featured'] = array('width'=>928, 'height'=>350); // big images for fullsize pages and fullsize 2D & 3D slider $avia_config['imgSize']['portrait'] = array('width'=>305, 'height'=>350); // medium preview pic for portrait pictures
It generates the proper height images, but I still have a 7 pixel shift up and down as the slides change, here: http://www.littlegraphicsengine.com/wpcms/
I'm pretty sure I need to adjust the CSS somewhere or maybe slideshow settings code, but I can't find anything (using FF Firebug) that is different for the height between the two types of slides.
