Hello, I'm stuck at a problem in another script.. I'm so far just at the point of trying to get a image file to upload.

The code in hand thus far.

          relative to where script is run ==*/
   
    $uploaddir = ".";

    $pext = getFileExtension($imgfile_name);
    $pext = strtolower($pext);
    if (($pext != "jpg")  && ($pext != "jpeg"))
    {
        print "<h1>ERROR</h1>Image Extension Unknown.<br>";
        print "<p>Please upload only a JPEG image with the extension .jpg or .jpeg ONLY<br><br>";
        print "The file you uploaded had the following extension: $pext</p>\n";

        /*== delete uploaded file ==*/
        unlink($imgfile);
        exit();
    }

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST" enctype="multipart/form-data">

As well as the error in hand.
Which i can't figure at all why im getting.
[quote]ERROR
Image Extension Unknown.

Please upload only a JPEG image with the extension .jpg or .jpeg ONLY

The file you uploaded had the following extension:


Warning: unlink() [function.unlink]: Permission denied in e:\web\public_html\7thstar\upload2.php on line 104[/quote]

If you can tell me why I would be getting this error it would be much appreciated.
