A post whose source is plain text, rather than a link to the website where it originally came from.
This includes file uploads, where the source is simply the filename used by the uploader, and posts where the source is a written description of where the image came from. Written descriptions are often used for scans, self-uploads or commissioner uploads, and game CGs or other assets datamined from a game.
Non-web sources should be avoided whenever possible. If you obtained the image from a website, you should post a link to the website where you obtained the image.
