If image type A can contain viruses, and a contaminated image of type
A is opened in Emacs from a file with extension for image type B,
Emacs would fall for the virus, because it would detect the correct
type (A) and use the A libraries to handle it. The extension is only
used to decide whether the file is an image or not, not what kind of
image.
