    The content of the files should not be put to memory as that can be quite big. It should use temporary files for that as the content is not needed at all a temporary file make more sense.

If the first object is not recognised, the new Unavail shape will be used, which will then try the other options in turn, and for each attempt to load a Picture shape, and upon success it will load the data and disable the Picture shape's tools (to avoid confusion etc). Finally, if no object is recognised, a question mark image is shown, to indicate that the object is unknown.
