thank for your answer it can be a solution but I use a different page layout to display the galleries. they are linked from the gallery manager.
I thought it was possible to creat 2 galleries with the same path, but visibly the second gallery can’t find the images folder.
Why I want to do that ?
I use WPML for translate the website and I need to duplicate every pages and also galleries. But if I change a pictures I need to change in the 2 galleries that’s why I search to have the same path for the galleries.
