Thank you Hax,

You said this has something to do with a translation. What do I have to
change to make it work in case of the use of a translation (dutch)?

I added this code into my themes function.php, but there is no change in the way my gallery is showed when I navigate to it trough my album page. The link from the album page to my galleries are not changed.

Probably you can have a look at my album page:

Kind regards
