broken link to nonexistent local file in man page for "convert"

The man page for convert says:

For more information about the convert command, point your browser to
       file:///usr/share/doc/imagemagick//www/convert.html or
       http://www.imagemagick.org/script/convert.php.

The first link is broken and points to a file that does not exist in Ubuntu 12.04.

If the package for Ubuntu stores files in a different location than imagemagick's defaults, the documentation should be updated accordingly.
