echo exif_imagetype($_FILES['Filedata']);
if ($_FILES['Filedata']['size'] <= $MAXIMUM_FILESIZE) {
move_uploaded_file($_FILES['Filedata']['tmp_name'], "./temporary/

$type = exif_imagetype("./temporary/".$_FILES['Filedata']['name']);
if ($type == 1 || $type == 2 || $type == 3) {
rename("./temporary/".$_FILES['Filedata']['name'], "./images/
".$_FILES['Filedata']['name']);
} else {
unlink("./temporary/".$_FILES['Filedata']['name']);
}
}
$directory = opendir('./images/');
$files = array();
while ($file = readdir($directory)) {
