Kako da UPDATE sliku

[Mirina]

Cao, evo mene opet sa mojim problemima

Elem, pravim neki sajtic i sve je islo bez problema dok nije trebalo da napravim stranicu za edit. E sad, i to je islo bez problema sve dok nisam stigla do dela za editovanje ili update slike. Na stranici za edit mi se prikazuju 3 slike. E sad, kada promenim sve 3 slike ne bude nikakvih problema ali kada hocu samo 1 sliku da promenim, izbaci mi gresku. Evo i koda:

 <?php
        require ('mysqli_connect.php');
        $page_title = 'Edit';
        include ('header.html');
        
        // Check for a valid user ID, through GET or POST:
if ( (isset($_GET['id'])) && (is_numeric($_GET['id'])) ) { // From view_users.php
	$id = $_GET['id'];
} elseif ( (isset($_POST['id'])) && (is_numeric($_POST['id'])) ) { // Form submission.
	$id = $_POST['id'];
} else { // No valid ID, kill the script.
	echo '<p class="error">This page has been accessed in error.</p>';
	exit();
}
        
        if ($_SERVER['REQUEST_METHOD'] == 'POST') {

		
        //Potkresivanje svih primljenih vrednosti
        $trimmed = array_map('trim', $_POST);
        
        
        if (isset($_FILES['upload1'])) {
		
		// Validate the type. Should be JPEG or PNG.
		$allowed = array ('image/pjpeg', 'image/jpeg', 'image/JPG', 'image/X-PNG', 'image/PNG', 'image/png', 'image/x-png');
		if (in_array($_FILES['upload1']['type'], $allowed)) {
		
			// Move the file over.
			if (move_uploaded_file ($_FILES['upload1']['tmp_name'], "includes/uploads/{$_FILES['upload1']['name']}")) {
                                $i = $_FILES['upload1']['name'];
			} // End of move... IF.
			
		} else { // Invalid type.
			echo '<p class="error">Please upload a JPEG or PNG image.</p>';
		}

	} // End of isset($_FILES['upload']) IF.
        
        // Check for an error:
	if ($_FILES['upload1']['error'] > 0) {
		echo '<p class="error">The file could not be uploaded because: <strong>';
	
		// Print a message based upon the error.
		switch ($_FILES['upload1']['error']) {
			case 1:
				print 'The file exceeds the upload_max_filesize setting in php.ini.';
				break;
			case 2:
				print 'The file exceeds the MAX_FILE_SIZE setting in the HTML form.';
				break;
			case 3:
				print 'The file was only partially uploaded.';
				break;

				break;
			case 8:

				break;
			default:
				print 'A system error occurred.';
				break;
		} // End of switch.
		
		print '</strong></p>';
	
	} // End of error IF.
        
         if (isset($_FILES['upload2'])) {
		
		// Validate the type. Should be JPEG or PNG.
		$allowed = array ('image/pjpeg', 'image/jpeg', 'image/JPG', 'image/X-PNG', 'image/PNG', 'image/png', 'image/x-png');
		if (in_array($_FILES['upload2']['type'], $allowed)) {

Posto ne mogu da prekopiram ceo kod, zbog velikog broja karaktera, stavila sam samo onaj deo koji je vezan za slike
Gde gresim Hvala na strpljenju i razumevanju
