Beyond The Coven's forum features a media uploading system. When replying to a topic, simply drag and drop an image or media file into the reply field and it will be ready to post.
All your files are stored in your unique media library and can be accessed by pressing the "My Media" button.
Lastly, images load within a viewing window that can be cycled through in a comic-style format. All images within a topic can be browsed together in this format.
