+
+はじめに
+
+  w3m でインライン画像を表示する拡張です。以下に置いてあります。
+
+    http://www2u.biglobe.ne.jp/~hsaka/w3m/index-ja.html#img
+                                          patch/w3m-0.2.4-img-2.2.patch.gz
+                                          patch/README.img-ja
+
+機能
+
+  ・X11 上の端末(xterm,kterm,rxvt,...)上に画像(GIF,PNG,JPEG 等)を表示します。
+  ・img タグで指定されたインライン画像を表示できます。
+    width,height 属性に応じて必要な領域を確保してレンダリングします。
+    align 属性に対応しています。
+  ・Content-type: image/* な画像ファイルを直接表示できます。
+  ・map タグに対応しています。
+    area タグの shape, coords 属性を認識し、メニュー表示から選択できます。
+  ・img タグの ismap 属性に対応しています。
+    座標値を ?<x>,<y> として URL に追加して送ります。
+  ・input タグの type=image 属性で指定されたインライン画像を表示できます。
+    座標値を <name>.x=<x>&<name>.y=<y> として送ります。
+  ・非同期に画像を読み込みます。
+  ・画像をキャッシュできます。
+
+キー操作
+
+  DISPLAY_IMAGE
+      画像の読込/表示を再開します。
+  STOP_IMAGE
+      そのバッファの画像の読込/表示を停止します。
+  SET_OPTION  display_image=toggle
+      画像の読込/表示を切替えます。
+
+  デフォルトのキーマップはありませんので、~/.w3m/keymap に
+      keymap  X    DISPLAY_IMAGE
+      keymap  C-c  STOP_IMAGE
+      keymap  t    SET_OPTION  display_image=toggle
+  の様に記述して使用してください。
+
+コマンドラインオプション
+
+  -ppc <pixel>
+      一文字あたりの幅(pixel 値)を指定します。デフォルトは自動設定。
+      正しく設定されない場合は端末の font の大きさに必ず合わせてください。
+  -ppl <pixel>
+      一行あたりの幅(pixel 値)を指定します。デフォルトは自動設定。
+      正しく設定されない場合は端末の font の大きさに必ず合わせてください。
+
+オプションパネル
+
+  pixel_per_char
+      一文字あたりの幅(pixel 値)を指定します。デフォルトは自動設定。
+      正しく設定されない場合は端末の font の大きさに必ず合わせてください。
+  pixel_per_line
+      一行あたりの幅(pixel 値)を指定します。デフォルトは自動設定。
+      正しく設定されない場合は端末の font の大きさに必ず合わせてください。
+  display_image
+      インライン画像を表示します。デフォルトは ON。
+  auto_image
+      インライン画像を自動で読み込みます。デフォルトは ON。
+      OFF の場合は、コマンド DISPLAY_IMAGE で読み込みを開始します。
+  ext_image_viewer
+      コマンド VIEW_IMAGE('I')の場合や Content-type: image/* である
+      画像ファイルを外部ビューワで表示します。デフォルトは ON。
+      OFF の場合は、インライン画像として直接表示します。
+  image_scale
+      画像のスケールを指定します。デフォルトは 100(%)。
+      小さい font と共に使う場合には値を小さくすると有用。
+  imgdisplay
+      インライン画像を表示するためのコマンド。デフォルトは w3mimgdisplay。
+      下記の "w3mimgdisplay の設定" を参考にしてオプション設定してください。
+  imgsize
+      インライン画像の大きさを得るためのコマンド。デフォルトは w3mimgsize。

+
+  -x <offset_x>
+      端末上に画像を表示する X 方向の原点。デフォルトは 2 ですが、
+      xterm や kterm ではスクロールバーの幅を計算して加えようとします。
+      (正しく出来ないかもしれません。)
+      Eterm では 5 にすべきかもしれません。
+  -y <offset_y>
+      端末上に画像を表示する Y 方向の原点。デフォルトは 2。
+      Eterm では 5 にすべきかもしれません。
+  -bg <background>
+      端末の背景色。デフォルトは自動設定。
+      #RRGGBB で指定する場合は # をエスケープして設定してください。

+
+Introduction
+
+  This is the extension for w3m to support inline image.
+  The patch for w3m-0.2.4 is available on the following site.
+
+    http://www2u.biglobe.ne.jp/~hsaka/w3m/index.html#img
+                                          patch/w3m-0.2.4-2.2.patch.gz
+                                          patch/README.img
+
+Support
+
+  * Display inline image (GIF,PNG,JPEG, etc.) on terminals
+    (xterm,rxvt, etc.) of X11.
+  * Support inline image of <img> tag.
+    Support of attributes "width", "height", and "align".
+  * Direct display of image file which header is "Content-type: image/*"
+  * Support of <map> tag.
+    Support of attributes "shape" and "coords" of <area> tag. 
+  * Support of an attribute "ismap" of <img> tag.
+    "w3m" adds coordinate of the cursor as ?<x>,<y> to url, and sends url.
+  * Support of an attribute "type=image" of <input> tag.
+    "w3m" sends coordinate of the cursor as <name>.x=<x>&<name>.y=<y>.
+  * Asynchronous loading of image files.
+  * Using cache of image file as pixmap.
+
+Key functions
+
+  DISPLAY_IMAGE
+      Restart loading and drawing of images.
+  STOP_IMAGE
+      Stop loading and drawing of images in the current buffer.
+  SET_OPTION  display_image=toggle
+      Toggle loading and drawing of images.
+
+  These functions are not keybinded as default.
+  Specify the following keymaps in ~/.w3m/keymap.
+      keymap  X    DISPLAY_IMAGE
+      keymap  C-c  STOP_IMAGE
+      keyamp  t    SET_OPTION  display_image=toggle
+
+Comandline options
+
+  -ppc <pixel>
+      # of pixels per character. The default value is automatically
+      detected. Must fit the width of font of terminal.
+  -ppl <pixel>
+      # of pixels per character. The default value is automatically
+      detected. Must fit the height of font of terminal.
+
+Option panel
+
+  pixel_per_char
+      # of pixels per character. The default value is automatically
+      detected. Must fit the width of font of terminal.
+  pixel_per_line
+      # of pixels per character. The default value is automatically
+      detected. Must fit the height of font of terminal.
+  display_image
+      Display of inline image. The default is ON.
+  auto_image
+      Automatic loading of inline image. The default is ON.
+      If it is OFF, loading starts with a command DISPLAY_IMAGE.
+  ext_image_viewer
+      Use external image viewer, when a command VIEW_IMAGE or
+      view of image file which header is "Content-type: image/*".
+      The default is ON. If it is OFF, the image is directly displaied.
+  image_scale
+      Scale of image (%). The default value is 100(%).
+  imgdisplay
+      External command to display image". The default value is "w3mimgdisplay".
+      See "Setting w3mimgdisplay".
+  imgsize
+      External command to get size of image. The default value is "w3mimgsize".
+
+Required programs
+
+  * w3m-0.2.4
+    http://w3m.sourceforge.net/
+    http://sourceforge.net/projects/w3m/
+    http://prdownloads.sourceforge.net/w3m/
+  * Imlib-1.9.8 (1.9.10 is recommendable.)
+    libungif-4.1.0b1 is recommendable.
+
+Install
+
+  gunzip -c DIST/w3m-0.2.4.tar.gz | tar -xvf -
+  cd w3m-0.2.4
+  gunzip -c DIST/w3m-0.2.4-img-2.2.patch.gz | patch -p1
+  configure
+    # When you are asked "Inline image support (you need Imlib library)",
+    # answer "y".
+    # Select menu.
+  make
+    # To make "w3mimgdisplay" and "w3mimgsize", Imlib is required.
+  make install
+    # Must install "w3mimgdisplay" and "w3mimgsize" to $LIB(PREFIX/lib/w3m).
+
+Setting w3mimgdisplay
+
+  "w3mimgdisplay" has the following options. Set options to fit terminal.
+
+  -x <offset_x>
+      The X origin of display of image on terminal. The default value is 2.
+      If the terminal is "xterm", the width of scroll bar is added.
+      If the terminal is "Eterm", it may be better to specify 5.
+  -y <offset_y>
+      The Y origin of display of image on terminal. The default value is 2.
+      If the terminal is "Eterm", it may be better to specify 5.
+  -bg <background>
+      Background color of terminal. The default value is automatically
+      detected.  When the color is specified as #RRGGBB, escape '#'.
