What are ways to store more then 10GB (around 30,000) images for a slideshow on a website [closed]

I want to create a website that is basically a slideshow that takes each time a random photo from the folder (or database) and displays it for a couple of seconds. The thing is I have more than 30,000 photos and it is around 15GB, What would be the my options to store the images for this website considering that I would like to be able to add more photos in the future. Thank you all in advanced.
