How to make files on shiny server viewable on website?

I currently have a shiny server that has a lot of images stored on it, but are not yet viewable on the website. I was wondering what command / code I can use to make it so that it can essentially be like: “for every file in this folder, make a link to it on the site”.

I know where the directory of all the images are on the server, but that's about all I have currently to give out. If you need another information, feel free to message for clarification and I will do my best to help!
