Hopefully someone can make sense of this...

I NEED WEBSITE HELP

Okay, I'm not sure if there's an easy way to do this or not, but it's something I'd like to have.

On Furtopia, when you would load up a directory (.../art/, .../photos/, whatever), it would show all the images in the directory as thumbnails, making a simple and basic gallery.

I want to do this on my new webspace, but I do not know how. It was coded into every site on Furtopia, it's not with the one I'm on now. Is there a simple way to do this? Keep in mind, I can follow directions, but I don't know anything about server/backend stuff when it comes to websites and hosting and I don't want to risk borking something.

Essentially, instead of a list, I want thumbnails:



Or something similar to that, I think you get the jist. I don't want anything ~fancy~. Just the directory as a page of thumbnails that link to the images themselves.
