Una fantastica galeria hecha con Javascript, en la que al pulsar sobre la imagen, esta se aumenta y al volver hacer click sobre ella vuelve a su tamaño pequeño.
Ademas, las imagenes tienen un genial efecto rotatorio que da una vision 3D.
Para añadir esta galeria a nuestro blog o web, primero vamos a la plantilla y antes de </body> ponemos el codigo CSS.
Para instalarlo en vuestro Bloc solo tenéis que seguir estos pasos:
1 Un clic en “Plantilla”
2 Un clic en “Editar HTML”
Ahora se te abrirá el Editor HTML de tu plantilla
En este punto deberás presionar la tecla “Control” de tu teclado seguido de la tecla “F” para que aparezca el buscador integrado en la parte superior derecha de tu editor,
debes esperar unos segundos hasta que se muestre, aquí es donde tendrás que insertar el código para buscarlo e insertar los códigos correspondientes en el editor,
3 Busca el siguiente código
</body>
Y antes de </body> coloca el siguiente código:
<style type="text/css">
#contenedorfotos{position: relative;width: 600px;height: 500px;float:center;}
#screen {
position: absolute;float:center;
left: 0%;
top: 0%;
width: 100%;
height: 400px;
background: #000;
}
#screen img {
position: absolute;float:center;
cursor: pointer;
visibility: hidden;
width: 0px;
height: 0px;
-ms-interpolation-mode:nearest-neighbor;
}
#screen .tvover {
border: solid #fff;
}
#screen .tvout {
border: solid #222;
}
#bankImages {
display: none;
}
</style>
#contenedorfotos{position: relative;width: 600px;height: 500px;float:center;}
#screen {
position: absolute;float:center;
left: 0%;
top: 0%;
width: 100%;
height: 400px;
background: #000;
}
#screen img {
position: absolute;float:center;
cursor: pointer;
visibility: hidden;
width: 0px;

}
#screen .tvover {
border: solid #fff;
}
#screen .tvout {
border: solid #222;
}
#bankImages {
display: none;
}
</style>
Ahora añadimos en la plantilla los scripts antes de </head> y guardamos.

Por ultimo, ponemos este codigo en un Gadget cada vez que queramos mostrar la galeria. Donde pone IMAGEN, lo sustituimos por la url de la imagen que queramos.
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 id="contenedorfotos">
<div id="screen"></div>
<div id="bankImages">
<img alt="" src="IMAGEN"/>
<img alt="" src="IMAGEN" />
<img alt="" src="IMAGEN"/>
<img alt="" src="IMAGEN"/>
<img alt="" src="IMAGEN" />
<img alt="" src="IMAGEN"/>
<img alt="" src="IMAGEN"/>
<img alt="" src="IMAGEN"/>
</div></div></center>
<script type="text/javascript">
/* ==== start script ==== */
onresize = tv.resize;
tv.init();
