Perl::Critic::Policy::PG::RequireImageAltAttribute - Images created with the image method should have the alt attribute set.
The alt attribute is crucial for accessibility, especially for visually impaired users who rely on screen readers to understand the content of the problem. So all images added to a problem should have the alt attribute set. Note that it can be set to the empty string to indicate that the image is not essential to the meaning of the problem content. Generally it is better to use the PGML syntax for images [!alternate text!]{$image} rather than using the image method.
