As I said before, check the logs produced by the class!!!!Reply

I mean the log produced by the class. See the first item of the FAQ.Reply

You need to instantiate the class with a local image file, not a directory.

You first get all your file names in an array, and then loop through it, instantiating the class each time with each file name.
$files = array('pic1.jpg', 'pic2.jpg', 'pic3.jpg');
foreach ($files as $file) {
  $handle = new Upload($file);
  if ($handle->uploaded) {
    $handle->image_resize            = true;
    $handle->image_ratio_y           = true;
    $handle->image_x                 = 100;
    $handle->Process('destination_directory/');
  }
}

Thank you for your help and patience. Based on them could solve the problem.

In order to help more people that perhaps might have the same problem, post here my code to send pictures zipped:

$uploadcaminho='test';
$codigo='13';

// START UPLOAD .ZIP FILE
print "VERIFICANDO ARQUIVOS ENVIADOS";
if ($uploadcaminho) {
  print "FOLDER DESTINATION (".$uploadcaminho.") [FOLDER - OK]";
} else {
  die('FOLDER DESTINATION - ERROR');
}
if (is_numeric($codigo)) {
  print "CODE (".$codigo.")[CODE - OK]";
} else {
  die('CODE ERROR');
}
if (!file_exists("/home/folder/".$uploadcaminho)) {
  mkdir("/home/folder/".$uploadcaminho, 0755);
  print "/home/folder/".$uploadcaminho." [FOLDER CREATED - OK]";
} else {
  print "/home/folder/".$uploadcaminho." [FOLDER EXISTing]";
}

print "START UPLOAD FILES ...";

if ($_FILES['my_field']['error'] == 0) {
  move_uploaded_file($_FILES['my_field']['tmp_name'], "/home/folder/".$uploadcaminho."/".$my_field_name);
  rename("/home/folder/".$uploadcaminho."/".$my_field_name, "/home/folder/".$uploadcaminho."/".$codigo.".zip");
  $my_field_name = $codigo.".zip";
} else {
  die("ERROr ".$_FILES['my_field']['error']);
}

// START UNZIP
$zip = new ZipArchive();
$zip->open("/home/folder/$uploadcaminho/$my_field_name");
$zip->extractTo("/home/folder/$uploadcaminho");
$zip->close(); 
echo "FILE $my_field_name UNZIP SUCCESS";

//DEL UNZIP FILE
unlink ("/home/folder/teste/$my_field_name");
echo "FILE $my_field_name DELETED WITH SUCESS!";

// ---------- MULTIPLE UPLOADS ----------
  
$diretorio = '/home/folder/teste/';
$ponteiro  = opendir($diretorio);

while ($nome_itens = readdir($ponteiro)) {
    $itens[] = $nome_itens;
}
sort($itens);

foreach ($itens as $k) {
  if ($k!="." && $k!=".."){
    if (is_dir($k)) {
      $pastas[]=$k;
    } else {
      $arquivos[]=$diretorio.'/'.$k;
    }
  }
}

foreach ($arquivos as $file) {
  $handle = new Upload($file);
  
  if ($handle->uploaded) {
    $handle->image_resize              = true;
    $handle->image_ratio_y           = true;
    $handle->image_x                 = 100;
    $handle->Process($diretorio);
    
    if ($handle->processed) {
      echo '  file uploaded with success';
      echo '  ' . round(filesize($handle->file_dst_pathname)/256)/4 . 'KB';
      echo '  link to the file just uploaded: "../../fotos/galeria/teste/' . $handle->file_dst_name . ' : ' . $handle->file_dst_name . '';
    } else {
      echo '  file not uploaded to the wanted location';
      echo '  Error: ' . $handle->error . '';
      echo '  Log: ' . $handle->log . '';
    }

  } else {
      echo '  file not uploaded on the server';
      echo '  Error: ' . $handle->error . '';
      echo '  Log: ' . $handle->log . '';
  }
}

Colin,more issue:

How to get the width of the image being sent and whether it is greater than XX pixels, reduce.

This example s not function:
if($handle->image_x > 800) {
  $handle->image_resize = true;
  $handle->image_ratio = true;
  $handle->image_x = 800; 	//width
}
