Image File
An Image File is a file-kind type assigned to image files (.png, .jpg, .jpeg, .gif, .svg, .webp, .avif) registered in a local corpus. It is one of the built-in extension templates the local server ships with — images are among the most commonly referenced non-Sparqdown files (diagrams, figures, photos).
What the registry stores
The standard file metadata — filename-derived title and the sdg:ImageFile type assertion. Image bytes are never parsed; renderers resolve the image through its source address.
