Lightbox popup | WordPress.org

Due to the images potentially being panaoamic we set the image frame to 100% width which means there is no space outside it. You can limit it with the following CSS which will work in most cases:

.aui-carousel-modal .modal-dialog-centered{
    max-width: 75% !important;
}

I will try it.

Also our theme Kadence supports lighbox and i have seen that WordPress also will do that (or it does it already).

Wouldn’t be better work with all that and not with custom / buildin lightbox?
