Website for Images

I’m looking for a little help or suggestion for a plug in code. Here is what I’m trying to accomplish. I would like an internal website that I can display a slideshow of images. These images would be updated each week so it would be nice to have the slideshow update automatically when the pictures are added to a folder. We are looking for a solution in the workplace to display images on televisions in breakrooms for employee information. Any help is appreciated.
