# File name in the Publisher

External files are referenced at various points in the layout, mainly in the images. These can have the following formats:

- Absolute path in the file system: `/path/to/file.png`.
- Relative path in the file system: `../directory/file.png`.
- File within the search tree: `file.png`. Before starting, the current directory is searched recursively (see File organization).
- Absolute paths under Windows like `c:\Users\...\file.png`.
- file scheme: `file://c/Users/Joe%20User/file.png` or `file:///home/user/file.png`.
- http-scheme: `http://picsum.photos/400/300` or https: `https://picsum.photos/400/300` (Pro feature).

These file names can be used for Images, for XPath- and layoutfunctions as well as on the command line. So it is possible to start the Publisher with

    sp --dummy --data https://raw.githubusercontent.com/speedata/examples/master/technical/rotating/layout.xml

First the resource is cached on the local computer and then loaded from there.

| Sometimes the backslash (`\`) itself must be provided with a backslash (`\\`). This is mostly necessary at shell level, i.e. when passing arguments when calling the speedata publisher.
