I am using a wordpress photo gallery plugin and I am receiving the following error when I upload a photo.

Warning: getimagesize() [function.getimagesize]: Filename cannot be empty in /home/******/public_html/alr/wp-content/plugins/wp-photo-album/wppa.php on line 651



The .php file info is below.

PHP Code:

    // check if thumbs dir exists 
    if (!is_dir($wppa_dir . '/thumbs')) {
        mkdir($wppa_dir . '/thumbs');
    }
    
    foreach ($_FILES as $file) {
[B][COLOR=Red]Line 651[/COLOR][/B]        if (getimagesize($file['tmp_name'])) {
            $ext = substr(strrchr($file['name'], "."), 1);
        
$query = "INSERT INTO " . PHOTO_TABLE . " (id, album, ext, name, description) VALUES (0, {$_POST['wppa-album']}, '$ext', '{$file['name']}', '')";
            $wpdb->query($query);
            //echo $query;
            $image_id = $wpdb->get_var("SELECT LAST_INSERT_ID()");
            
            $newimage = $wppa_dir . '/' . $image_id . '.' . $ext;
            copy($file['tmp_name'], $newimage);

            if (is_file ($newimage)) {
                $uploaded_a_file = TRUE;
                if (is_numeric(get_option('wppa_thumbsize'))) {
                    $thumbsize = get_option('wppa_thumbsize');
                } else {
                    $thumbsize = 130;
                }
                
                wppa_create_thumbnail($newimage, $thumbsize, '' );
            } 
        }
    }
    
if ($uploaded_a_file) { echo '<div id="message" class="updated fade"><p><strong>Photos Uploaded.</strong></p></div>'; }

} 


Can someone please tell me how to fix this?

[function.getimagesize]: Filename cannot be empty

How is that hard to understand?
you have a call to getimagesize() with an empty parameter.

Maybe you should start by dumping $_FILES to find what you are feeding to getimagesize():

PHP Code:

foreach ($_FILES as $file) {
  if (getimagesize($file['tmp_name']))
