Aquí te dejo un truco para darle efectos a todas las imágenes de tu Hi5:

1.- Hacer clic MI PERFIL.

2.- Luego clic al lado derecho de "Estilo De Vida" donde dice "[Editar esta sección]" esta debajo de sus datos básicos.

3.- Luego en la parte inferior esta un cuadro llamado "Acerca de mí: Escribe una descripción corta de ti mismo. Puedes ingresar código HTML o CSS." (SI TIENES OTROS CÓDIGOS NO LOS BORRES, SOLO COLOCA UNO DEBAJO DEL OTRO), elige la imagen que mas te guste, copias el código y lo pegas en el recuadro y por ultimo clic a "Guardar Perfil" y ver el resultado.
