help:metatags

Meta tags are tags that convey information about an image outside of what is visible in it. For the search syntax feature of the same name, see help:cheatsheet.

The basic rule of thumb is that a meta tag describes what a post is, while general tags describe what a post contains. This has some exceptions, such as JPEG artifacts or scan artifacts.

Examples of things meta tags are used for:

• Image resolution (lowres, highres)
• Post medium (animated, photo (medium))
• Edits (third-party edit, stitched)
• Source information (non-web source, third-party source)
• Tagging information (tagme, character request)
• Post origin (commission, fan request)

For a list of meta tags, see tag group:metatags.
