The problem is that you have to specify the file format when you call the plot method. That is, replace 
print $img->plot;

[download]

with 

print $img->plot('png');

[download]

Yes, the documentation is wrong, and the module should complain or have a default if no format is provided.

Added: The format you provide has to be the name of one of the "Image Data Output Methods", as listed in the GD documentation.
