Adds WIDTH and HEIGHT attributes to IMG tags in HTML files

 The imgsizer script automates away the tedious task of creating and
 updating the extension HEIGHT and WIDTH parameters in HTML IMG tags.
 These parameters help browsers to multi-thread image loading, instead of
 having to load images in strict sequence in order to have each one's
 dimensions available so the next can be placed. This generally allows
 text on the remainder of the page to load much faster.
 .
 The package needs either the imagemagick package or both the file and
 libjpeg-progs packages.
