Hola me descargue el jquery file upload y lo instale para probarlo en mi localost con Xampp y con ese cargador de archivos uno puede subir cuantas imagenes quira...lo que sucede es que yo selecciono mas de dos imagenes y solo me carga nada mas dos! o sea solo me guarda en el directorio las dos primeras y el resto hace como si las cargo y todo pero en realidad no cargo nada, les muestro el codigo que uso:

y con esto proceso los datos que me llegan

alomejor le falte uno que otra llave pero es por unas validaciones que hago de por ejemplo if(isset($_SESSION['log'])){

Código PHP:

// ---------- MULTIPLE UPLOADS ----------
    if($fi==""){
    
        echo "  Esta vacio";
        exit;
        }
    // as it is multiple uploads, we will parse the $_FILES array to reorganize it into $files
    $files = array();
    
 
    foreach ($fi as $k => $l) {
        foreach ($l as $i => $v) {
            if (!array_key_exists($i, $files))
                $files[$i] = array();
            $files[$i][$k] = $v;
        }
    }
 
    // now we can loop through $files, and feed each element to the class
    foreach ($files as $file) {
        $ra=microtime(sha1(sha1(md5(rand(9999999999,9999999999)))));
        
        if($file['type']==""){
        echo "Esta vacio";
        exit;
        }
if(($file['type']!="image/png")&&($file['type']!="image/jpeg")&&($file['type']!="image/gif")){
echo "El tipo de archivo no es de los permitidos!";
exit;   
}
 
 
        // then we check if the file has been uploaded properly
        // in its *temporary* location in the server (often, it is /tmp)
$foo = new Upload($file);
if ($foo->uploaded) {
  // save uploaded image with a new name
  $foo->file_new_name_body = $ra;
  $foo->image_resize = true;
  $foo->image_convert = 'jpg';
  $foo->image_x = 700;
  $foo->image_ratio_y = true;
  $foo->Process($dir_dest);
  if ($foo->processed) {
 
  } else {
 
  }
  
  $foo->file_new_name_body = $ra;
  $foo->image_resize = true;
  $foo->image_convert = 'jpg';
  $foo->image_x = 80;
  $foo->image_ratio_y = true;
  $foo->Process($dir_dest3);
  if ($foo->processed) {
 
  } else {
 
  }
  // save uploaded image with a new name,
  // resized to 100px wide
  $foo->file_new_name_body = $ra;
  $foo->image_resize = true;
  $foo->image_convert = 'jpg';
  $foo->image_x = 200;
  $foo->image_ratio_y = true;
  $foo->Process($dir_dest2);
  if ($foo->processed) {
     $query = "INSERT INTO imagenes(id_usuario,id_album,ruta_normal,ruta_thumb) VALUES ('$id_usuario','$id_album','$ra','$ra')";
           mysql_query($query) or die(mysql_error());
           if(mysql_affected_rows()>0){
            echo "Imagen subida satisfactoriamente!";
           }else{
              echo "La imagen no pudo ser subida";   
           }
    $foo->Clean();
  } else {
    echo 'error : ' . $foo->error;
  }
}
 

eso es todo! no entiendo que sucede porq no sube mas de dos archivos
