how to open a larger picture?

Set the links in Table VI to lightbox. No further plugin required.

Thank you for your reply.
As I do not understand English, I did not change any settings.
I tried to change the settings in Table VI for the link single photo.
But I’m not satisfied, I want the link opens the slideshow in the same page as the photo, instead of leading to another predetermined page.
Is this possible, and how?

I want the link opens the slideshow in the same page as the photo

It is of no use to have the link to the same page, because the size of the wppa-container stays the same: you will not see a larger image but the image in a slideshow of the same size.

Enter the shortcode for a slideshow ( new style, like: [wppa type="slide" album="2"][/wppa] ) and add the photo id for the photo you want to start the slideshow with. Example:

[wppa type="slide" album="2" photo="243"][/wppa]

Sorry, but I think you have not understood my problem. I’m not asking how to make a large slideshow!

I speak of individual photos that illustrate articles or pages: I put several pictures spread to several parts of the page. You will understand with a link:https://www.mon-coin-de-bourgogne.fr/visites-touristiques/brancion/
On this page, the first picture is inserted with this code:%% WPPA%% %%photo = 40%% %% size = 400%%
The other pictures are stored somewhere other than WordPress, but later, they will be inserted with WPPA.

I want that clicking on the first photo (or any picture inserted with the code WPPA%% ), a pop-up window opens like a lignhtbox to scroll through the pictures on the current page, but more large. And clicking “close”, it returns on the page.

I hope that you understand what I want … but perhaps that’s not possible with WPPA!
