Si queremos mostrar varias imagenes en nuestro blog o web, que mejor que contar con un Slider, de los cuales existen muchos y de diversos tipos.
El que te presento en este caso, esta realizado con Javascript y es muy sencillo de implementar. Tan solo debes copiar el codigo y añadirlo alli donde quieras mostrarlo.
1-Un clic en “Diseño”
2-Clic en “Añadir un gadget”
3-Busca el widget que dice “HTML-Javascript” y ábrelo
4-Coloca el siguiente codigo en el interior
<center><div style="width:500px;height:px;-webkit-border-radius: 20px;-moz-border-radius: 20px;border-radius: 20px;background-color:#000000;padding:15px;">
