If there are no errors, "images" will be filled with a list of
node IDs and their corresponding URLs for the displayed images, and "status"
will be left empty. After 30 days, the picture assets will stop working.
It's important to note that the picture map could include null values. This
suggests that the node's attempt to render has failed. The lack of a node
id or other factors, such as the absence of renderable components, may be
responsible. Whether or not the render was successful, it is assured that
any node that was requested for rendering will be represented in this map.
