We can add visual sparkle to our page by giving icons to the files with the AddIcon directive. Apache has more icons than you can shake a stick at in its ... /icons directory. Without spending some time exploring, one doesn’t know precisely what each one looks like, but bomb.gif will do for an example. The icons directory needs to be specified relative to the DocumentRoot directory, so we have made a subdirectory ... /htdocs/icons and copied bomb.gif into it. We can attach the bomb icon to all displayed .html files with this:

...
AddIcon icons/bomb.gif  .html

AddIcon expects the URL of an icon, followed by a file extension, wildcard expression, partial filename, or complete filename to describe the files to which the icon will be added. We can iconify subdirectories off the DocumentRoot with ^^DIRECTORY^^, or make blank lines format properly with ^^BLANKICON^^. Since we have the convenient icons directory to practice with, we can iconify it with this:

AddIcon /icons/burst.gif ^^DIRECTORY^^

Or we can make it disappear with this:

...
IndexIgnore  icons
...

Not all browsers can display icons. We can cater to those that cannot by providing a text alternative alongside the icon URL:

AddIcon ("DIR",/icons/burst.gif) ^^DIRECTORY^^

This line will print the word DIR where the burst icon would have appeared to mark a directory (that is, the text is used as the ALT description in the link to the icon). ...
