I want my WordPress image gallery to show only the first image?

My goal is to create a WordPress photo gallery which only shows the very first image of the gallery on the page and when a user clicks it , It pops up a lightbox with the rest of the images.

Moreover It has to be an easy-to-use solution because people will use it with no or minimal IT knowledge.

Is there any plugin or handy solution for my problem ?

I am looking forward for your answers .

Thank you ! šŸ™‚

using NextGen can work.
