Estoy Aqui Aura Quiero saber Como ponerle un fondo a mi tema osea otra imagen ejemplo [Imagen: fondosp.png] en esta imagen ven un tema y la imagen de fondo es Battlefield yo quisiera saber como agrego una imagen de fondo

Hola,

Entra en el panel de administración y edita el fichero global.css de tu theme.

Ve a "Editar hoja de estilo: modo avanzado" y donde pone:
body{
....
}

tienes que añadir:
background-image: url(tuimagen);
background-repeat: repeat-x;

y te debería quedar algo así:
body {
background: #efefef;
background-image: url(/images/vida/fondo.jpg);
background-repeat: repeat-x;
color: #000;
font-family: Verdana, Arial, Sans-Serif;
font-size: 13px;
text-align: center; /* IE 5 fix */
line-height: 1.4;
margin:0px;
}

Eso es un ejemplo, pero es ahí donde debes poner la imagen de fondo.

Un saludo.

Tienes mal la declaración del estilo para body{}

Tu tienes esto:

body {
}

background: #ffffff url(http://img38.imageshack.us/img38/6263/bautifield.jpg);
background-repeat: no-repeat;
background-position: center center;
background-attachment: fixed;
}

Y deberias tener esto:
body {
background: #ffffff url(http://img38.imageshack.us/img38/6263/bautifield.jpg);
background-repeat: no-repeat;
background-position: center center;
background-attachment: fixed;
}

Es decir, te sobra el primer } que tienes.
Te marco en rojo lo que tienes que quitar:
body {
}

background: #ffffff url(http://img38.imageshack.us/img38/6263/bautifield.jpg);
background-repeat: no-repeat;
background-position: center center;
background-attachment: fixed;
}

un saludo.

Ok Gracias ahora si me funciono (^^.)

Ha sido un placer !!
