Help with file upload

[Brusca]

Hi,
Just doing a simple image (jpeg) upload to a directory. Have a script which works fine on one server but comes up with 'wrong file type' on another server.

The server that works has php5 installed, the other is 4.2.2 but I am sure what I have should work on both.

$allowed_types = array('image/jpg','image/jpeg','image/gif','image/png');
   if(isset( $Upload )) 
    { 
        		if(in_array($_FILES['imagefile']['type'],$allowed_types))

    {  
	$_FILES['imagefile']['name'] = "brusca.jpg";
        copy ($_FILES['imagefile']['tmp_name'], "../directory is set for chmod 777/".$_FILES['imagefile']['name']) 
            or die ("Could not copy");  
        echo ""; 
        echo "Name: ".$_FILES['imagefile']['name'].""; 
        echo "Size: ".$_FILES['imagefile']['size'].""; 
        echo "Type: ".$_FILES['imagefile']['type'].""; 
        echo "Copy Done...."; 
        }  
    else  
    { 
        echo ""; 
        echo "Could Not Copy, Wrong Filetype (".$_FILES['imagefile']['name'].")"; 
    } 
}

anything server wise (.ini) that may be messing with this??

typically, when I do file uploads, I verify the file types using GetImageSize()

Also, I think this might be a safer method. I'm not entirely sure on this point, but I think that an enterprising user can fake the file types sent via upload, and confuse PHP. The most secure way of verifying an image is by checking the image itself. Either way, the above function should do it for you.
