== Image metadata ==
{{note|type=warn|Images currently need to be compiled into the game files.  Simply including them in your level directory is not sufficient and attempting to reference such a file will result in the game crashing on startup.}}
{{note|type=info|You can reuse images from existing levels using normal path navigation (eg: <code>../sort/0.png</code> for a slice of pie on a plate).

This should not be considered a viable long-term solution as your level becomes dependent both on the other level(s) not changing their images, and also on the game not enforcing directory locality in the future.  It can be a good placeholder during development however, and if your level is accepted into the base game you can replace the temporary image references with valid ones at that time.}}

* <code>id</code> An identifier that can be used by the test code to reference the image object.
* <code>filename</code> The name of the file to load.
* <code>x</code> The horizontal offset of the image from the center of the panel (negative values are left).
* <code>y</code> The vertical offset of the image from the top of the panel (negative values are up - above the panel itself).
* <code>hidden</code> If true, the image will not be displayed until the test code changes this property to false.
