Colocar Slider de Imágenes en Blogger

En esta ocasión les dejo la receta para colocar imágenes en slider en tu blog, para esto solo debemos seguir estos 3 pasos:

1. Entrar en la edición HTML del blog y buscar la etiqueta </body> y pegar el siguiente código antes de la etiqueta:





<script src=’https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js’ type=’text/javascript’/>

<script type=’text/javascript’>
jQuery(window).load(function() {

2. Modificar las hojas de estilos (ccs), para ello buscamos la etiqueta ]]></b:skin> y pegar el siguiente código justo antes de la etiqueta:

/* NIVO SLIDER STYLES */

#slider-container {
margin-bottom: 50px;
}

.nivoSlider {
position:relative;
}

.nivoSlider img {
position:absolute;
top:0px;

}

.nivoSlider a.nivo-imageLink {

left:0px;
width:100%;
height:100%;
border:0;
padding:0;
margin:0;
z-index:60;
display:none;
}

.nivo-slice {

}

width:100%;
z-index:89;
}

.nivo-caption p {

text-align: center;
}

.nivo-caption a {

}

.nivo-html-caption {

}

.nivo-directionNav a {

top:45%;
z-index:99;
cursor:pointer;
}

.nivo-prevNav {
left:0px;
}

.nivo-nextNav {

}

.nivo-controlNav a {
position:
relative;
z-index:99;
cursor:pointer;
}

.nivo-controlNav a.active {
font-weight:bold;
}

3. Agregar un Gadget donde queremos que se coloquen las imágenes con el siguiente código:

<b:if cond=’data:blog.pageType != &quot;item&quot;’> <b:if cond=’data:blog.pageType != &quot;static_page&quot;’> <div class=’crosscol’> <div id=’slider-container’>
<div id=’slider’>
<a href=’https://www.facebook.com/pages/Aguamala-Reggae-Band/108174285486′ target=’_blank’ title=’AGUAMALA’>
<img alt=» src=’https://dl.dropboxusercontent.com/u/67252744/Reggaecaracas/slide/Aguamala3.jpg’ title=’Reggae’/>
</a>
<a href=’http://www.lebronch.com/’ target=’_blank’ title=’LEBRONCH’>
<img alt=» src=’https://dl.dropboxusercontent.com/u/67252744/Reggaecaracas/slide/Lebronch.jpg’ title=’Another image in a post’/>

</a>
<a href=’http://www.nauvinlakay.com’ target=’_blank’ title=’NAUVINLAKAY’>
<img alt=» src=’https://dl.dropboxusercontent.com/u/67252744/Reggaecaracas/slide/NouVinLakay.jpg’ title=’Testing HTML elements’/>
</a>
<a href=’http://www.onechot.com’ target=’_blank’ title=’ONECHOT’>
<img alt=» src=’https://dl.dropboxusercontent.com/u/67252744/Reggaecaracas/slide/onechot.jpg’ title=’Category Hierarchy’/>
</a>
</div>
<br clear=’all’/>
</div>
</div> </b:if> </b:if>

TIPS IMPORTANTES:
  1. Lo que está en rojo indica el URL que redirigirá la imagen y lo que está en azul es el URL donde está la Imagen.
  2. Si no funciona el Slider prueba cambiar el paso 1 y poner el código delante de la etiqueta </header>.
  3. Todas las imágenes deben tener exactamente el mismo tamaño.
