problema con html con dos style.css y rel="stylesheet"

[caiman01]

Buneas tardes,
tengo mi html de mi web con su style.css que funciona sin problemas.

<link href="style.css" rel="stylesheet" type="text/css" />


ahora necesito una galeria de imagenes, y el ejemplo q he descargado de internet trae otra linea css con el mismo rel="stylesheet"...

<link href="css/lightbox.css" rel="stylesheet" />

el tema es que los efectos, tanto del fade como de la pagina ya no salen de forma correcta...

a ver si alguien me puede ayudar que tengo cierta urgencia con la web....

gracias
