[mod says:] You can link to videos and pictures in your profile or in appropriate threads. But there isn’t really an outlet on the site to upload content, if that is what you mean. If you want to discuss videos/show images etc, you can upload them in the chat room and people will see them automatically due to the chat room format. Also, if the image/video you are linking to is “adult content”, be sure to put a warning of “NSFW” next to the link. NSFW = not safe for work
