Create a galery with thumbnail

so in the first image with the thumbnails, you want it to be a carousel with multiple thumbnails for each project?

any idea ?

Sorry tought I replied to you on the previous comment.. here's my answer from last time :

When I click on the thumbnail of the first image, I would like it opens a gallery where I could write some infos about the project and also get the others images that the client sees the whole project in a gallery, not specificly a carousel (I know how the change the design but not how to get Thumbnail that opens a new gallery on a new page or into a new "canvas").

Thanks for your answer buddy.
