Description

The ICONS resource is used to specify the icons that represent the different content-types of messages. This resource is used to define the possible expanded values of the $ICON$ resource variable.

The ICON resource can only be defined via the resource file element. The format of each line in the ICONS element is as follows:

content-type:url

The definition of each item is a follows:

content-type

MIME content-type that an icon should be associated to. Examples: text/plain, image/jpeg. An icon can be associated to a base type by using a * as the sub-type. Examples: text/*, image/*. The default icon can be specified by using a content-type of */*.

url

The URL of the icon. Example: http://host/icons/text.gif, /icons/image.gif.

The url can be prefixed with a width and height specification to provide rendering hints to browsers. The syntax for specify the width and height is as follows: [WxH], where W is the width and H is the height. The following is an example URL setting with width and height specification: [20x22]/icons/image.gif.

The width and height values map directly to the WIDTH and HEIGHT attributes of the HTML IMG element when $ICON$ is used. Specifying the width and height decreases the rendering time of a page since browsers do not have to wait to fetch the image to determine how much area to provide for rendering.

In order to have icons appear in your pages, use the $ICON$ resource variable. For example:

<LiTemplate>
$ICON$ <strong>$SUBJECT:40$</strong>
<em>$FROMNAME$</em><br>
</LiTemplate>

The $ICON$ variable expands to the IMG HTML element with the appropriate URL in the SRC attribute to the icon. The ALT attribute of the IMG element contains the content-type of the message, surrounded by []'s, for use with text based browsers. If the width and height values have been defined for the given URL as described earlier, they will map to the WIDTH and HEIGHT attributes.

The $ICONURL$ resource variable may be used if you want redefine the format of the IMG element. For example:

<LiTemplate>
<img src="$ICONURL$" alt="*">
<strong>$SUBJECT:40$</strong>
<em>$FROMNAME$</em><br>
</LiTemplate>
