			if($imagesize[0]>$imagesize[1])
			{
			if($imagesize[0]> 400)
			{
				$w = 400;
				$h = ($imagesize[1]*400)/$imagesize[0];
			} else
			{
				$w = $imagesize[0];
				$h = $imagesize[1];
			}
			} else
			{
				if($imagesize[0] > 400)
				{
				$w = 400;
				$h = ($imagesize[0]*400)/$imagesize[1];
			}else
			{
				$w = $imagesize[0];
				$h = $imagesize[1];
