Oh, I forgot that! The spanish translation of the plugin is a bit confusing in this part :/
Well, now I have the pages with their respective images. Thank you :D
And now, I don't know why, when I click to the next page the language suddenly it switches to ES (the default lang is EN).
When I click to the previous page the page is it stays in EN (when it changes to ES, the pages are and the whole site is in ES). I have deactivated the automatic translation... regenerated the permalinks...
Also... there is someshow to keep the old publication date then you post a new translation?
Thanks for the help :)
