Tengo este codigo para subir multiples imagenes, funciona muy bien, pero no renombra el archivo al subir
Código PHP:

$upload_image_limit = 5; // How many images you want to upload at once?
$upload_dir = "./images/"; // default script location, use relative or absolute path
$enable_thumbnails = 1 ; // set 0 to disable thumbnail creation
