Well, it seems like it was a html code problem. I was using HTML for add style to the text.
First i duplicate the slide #1 and then i did change image and text to create slide #2.
What hapenned exactly? I don´t know. But i left this here in case results usefull for another one.
Great plugin!
Thanks
Firebug shows me that the slider it´s calling only one image, either they are two slides.
