Lightbox and sharing gallery

Hello
First i am french so sorry for my english 🙂
and second thanks for your job 🙂
now my question :

1 – i want to know how can i change all the word used in this plug for french ( perhaps a list somewhere i can change) if it is not too difficult i can translate it: )

2 – when i create a personal buddypress gallery like a user with 5 photos
when i click on the gallery main image i have a pop up ajax with my first image and a comment on the right
how can i do to have a list of the thumbnail of my images and not the first in ajax and after a pop up ajax like you but with the space white on the right for comment erased and to have just the image not comment

3 – can i create share gallery directory… that users can use to upload images
ex not to have “gallery_auto_user1” “gallery_auto_user2” “gallery_auto_user3”
but one gallery “gallery_auto” and all user can upload their auto image in without being able to erase the image of the other users

thx
