Warning: getimagesize(home/doyouwa/public_html/bbb/hosted_images/1.gif): failed to open stream: No such file or directory in /image_host.php on line 196
unable to get image size

Also I think you need to remove the / in the $dir/ in that copy

//upload image if all correct
	@copy($_FILES['img'][tmp_name], "$dir/".$_FILES['img']['name']) ;

//check the image size delete if too big and print error
	if(!$size = getimagesize($dir .$host_filename)) die('unable to get image size');
