Using Yoxview

Finally I solved this :) I'm writing a post about it in my blog but in Spanish but I'm going to give you an advance here:
Once you have installed the module you have to:
- Create a content type for yoxview, for instance YoxGallery: Structure -> Content Types -> Add content type
- Create a type Gallery for the content type you created, in Manage Fields you have to indicate that field and widget type is Image. Next, click edit and enter into number of Values a value distinct to one.
- Go to the Manage Display tab, and for the type Gallery you have to indicate that the format is yoxview and the style "thumbnail"
- Finally, go to Content -> add Content -> YoxGallery indicate a title if you want and upload your images.

I'm sorry if my English is not too good but I hope this hepl you.
