		rfrs_obj.style.height = String(rfrs_max_height) + 'px';
		document.all ? rfrs_obj.style.cursor = 'hand' : rfrs_obj.style.cursor = 'pointer';
	}
}

Edit file includes/class_bbcode.php and find:

return '<a target="_blank" href="' . $link . '" rel="lytebox"><img src="' . $link . '" border="0" alt="" /></a>';

Replace with:

return '<a target="_blank" href="' . $link . '" rel="lytebox"><img onload="rfrs(this, 200, 200)" src="' . $link . '" border="0" alt="" /></a>';

Save all

Note: to change max width and max height for resize, just change the value in includes/class_bbcode.php at rfrs(this, 200, 200)
