これには2つの内容があります:どうやって HTML内で画像を clickableに指定するのか 、Mosaic, Chimeraなどのクリックを伝送することができるクライアントから戻ってきたものによって何かを行なうには、サーバをどう設定したらいいのか、です。

image mapを使うためには、mapファイルを作らなければなりません。これは手で行なってもいいし、WYSIWYGツールを使うこともできます。私はこのようなツールとして、Microsoft Windowsおよび X Window System用の Mapedit (URL http://sunsite.unc.edu/boutell/mapedit/mapedit.html )を作成しました。また、他のツールも利用できます (URL ?)。
注意 (重要): image mapの作成は、サーバの管理者と本当の webサーバが必要です。必要なツールがそろう前に mapを作って、時間を無駄にしないように。
訳注:日本語の解説として、NTTの高田敏弘さんによる 「NCSA httpd-1.0を用いたISMAP機能の設定方法」 (URL http://www.ntt.jp/people/takada/docs/ismap.html) があります。There are really two issues here: how to indicate in HTML that you want an image to be clickable, and how to configure your server to do something with the clicks returned by Netscape, Mosaic, and other clients capable of delivering them. Client side imagemaps, a new feature of Spyglass Mosaic, Microsoft Internet Explorer and Netscape (2.0 and beyond), change this picture by allowing imagemaps to be created as part of an HTML document without the need for special server software.
One of the best resources available on the subject is the Imagemap Help Page <URL:http://www.hway.net/ihip/>, maintained by Steve Rogers.
You can read also about image maps and the NCSA server at <URL:http://hoohoo.ncsa.uiuc.edu/docs/tutorials/imagemapping.html> ). Also see Joseph Walker's collection of imagemap resources (URL is <URL:http://www2.ncsu.edu/bae/people/faculty/walker/hotlist/imagemap.html > ).
Using imagemaps requires that you create a map file; you can do this by hand or with a WYSIWYG tool.
VERY IMPORTANT: Creating server-side imagemaps, which all web browsers understand, requires a real web server (not an FTP server) and a cooperative web server administrator. It is not usually as simple as wrapping a link around an IMG SRC tag and adding the ISMAP directive; the server must also be told about the map file, and the way to accomplish this varies from server to server. So read your server documentation, and don't waste time making maps before making sure you have the necessary tools to deliver them.
Several of the newer browsers, notably Microsoft Internet Explorer, Spyglass Mosaic and Netscape 2.0 and later, support "client-side" imagemaps. This is a Good Thing, because the imagemap is part of the HTML page and a server need not be involved. However, keep in mind that not every user has a browser that supports such imagemaps. Client-side imagemaps can be used side by side with old-fashioned server-side imagemaps,which are used if the browser does not understand the newer type. Many of the imagemap editors listed below support the creation of both types of maps.
