Reference: *Images Module at the W3C
The Images Module is used to specify images to be displayed within the document. The img
element is like a more specialised version of the object element, which can
also be used to include images in an XHTML 1.1 document. The img element
is more commonly used, however.
Note: The W3C calls this module the Image Module, rather than the Images Module, but I have added the extra 's' because a Search of this site for a module matching 'Image' would also return results for the Client-side Image Map Module and Server-side Image Map Module, whereas a search for a module matching 'Images' would not.
