Prevent images from strech

I got the same problem as superflymonkeyboy and could resolve it by not putting any height and width in the shortcode an changing line 166-171 in “jj_ngg_jquery_cycle.php”:

if($width != '' && $height != '')
        {
          $width_d = " width=\"" . $width . "\"";
          $height_d = " height=\"" . $height . "\"";
        }

to

if($width != '' && $height != '')
        {
          $width_d = " width=\"" . $width . "\"";
          $height_d = " height=\"" . $height . "\"";
        } else { //use image dimensions
          $width_d = " width=\"" . $image->meta_data['width'] . "\"";
          $height_d = " height=\"" . $image->meta_data['height'] . "\"";
		}
