Description:
------------
I have a resizeimage page taht I use to display intermediate size pics on my viewer page.  It resizes one image every time it is ran.  After a few hours apache is taking up like 600 meg of ram and the page will not load anymore.

Reproduce code:
---------------
$dst_img = imagecreatetruecolor($dest_w, $dest_h);
	imagecopyresampled($dst_img, $src_img, 0, 0, 0, 0, $dest_w, $dest_h, $srcsize[0], $srcsize[1]);
	switch($srcsize['mime'])
	{
		case "image/jpeg":
			header("content-type: image/jpeg");
			imagejpeg($dst_img); 
			break;
		case "image/png":
			header("content-type: image/png");
			imagepng($dst_img); 
			break;
		case "image/gif":
			header("content-type: image/gif");
			imagegif($dst_img); 
			break;
	}
	
	//  Destroy images
	imagedestroy($src_img);
	imagedestroy($dst_img);

Expected result:
----------------
That is part of the code.  The beginning part opens the file and gets the info about it to know which one to use.  I would expect using imagedestroy at the end for both images would remove it from memory.

Actual result:
--------------
Some memory is regained, but not all the time.
