Upload Image with a file URL and show dynamically on Frontend

Please help! I am a newbie on Wordpress. I am looking for a workaround or plugin which can help me upload an Image on the backend (like thorugh WP Frontend Admin plugin. and on the Frontend, it comes out dynamically as clickable thumbnails which directs to the File path upon clicking.

something like this website https://www.sofi.life/faithnews/

it is fairly easy to do it through elementor, but I am looking for a dynamic work around so the client can do it on their own, uploading it through a custom dashboard and it showing dynamically on the frontend website
