No, there isn't really. A web server typically does not tell you about all the files it knows about. When you request some URL, you are often not even browsing actual files, but are just making the server invoke some scripts that in the end give you some HTML back. In that HTML you would find references to images etcetera, which are often real files on the web server (but sometimes are just scripts as well), but in general there's no way to make the web server give you a list of all other images.
There are ways to get a lot of information from a web server, like ways to download many pages and its media from some website. But that's still all based on the links that the web server exposes itself: programs simply follow all the links and get as much information they can from that. That's basically also how search engines work.
(Sometimes a server would show you all files in a folder if you really ask for a folder name. But that's often prohibited.)
