+  * 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.
+

+Setting w3mimgdisplay
+
+  "w3mimgdisplay" has the following options. Set options to fit terminal.
+
+  -x <offset_x>
