Album : error image & URL not optimized

Hello,

I notice a problem with my albums.
Indeed, I can not get a single URL to be able to share the album with people.

1) the URL is not at all optimized, I have this kind of URL: http://www.example.fr/galerie-photos/evenements-fetes?type_0=gallery&album_gallery_id_0=114&bwg_previous_album_id_0=5,5&bwg_previous_album_page_number_0= 0.0

2) The most important point when I share this link: the first page displays the images of my album but as soon as I change to the second page or so on, the album changes and these are other images that s’ Display!

Do you have a solution ?
Thanks
