Link Icons are an optional new feature of Php Wiki. When activated, icons will be displayed in front of URLs to indicate the type of link.
http link
generic internet link
Inter Wiki link
https link
mailto link
ftp link
Note: Some of the default icons use the alpha channel feature of
the 
PNG image format
for smooth rendering on any page color or textured background. Older
browsers may not display all the images properly.
Examples
The following examples will display with the above link icons only if the administrator has enabled this feature.
Inter Wiki links
- Inter Wiki link PhpWiki:InterWiki
- A named Inter Wiki read WhyWikiWorks at c2.
URLs
- Email address PhpWiki-talk mailing list
- Normal http link PhpWiki's Home Page
- Secure http link PhpWiki's Home Page
- File transfer ftp://ftp.sourceforge.net/
A generic icon is shown for other less common link types.
Link Icons will only display when the URL protocol is one which Php Wiki is allowed to link to. The following examples won't show any icons and Php Wiki won't automatically provide double-clickable links either, unless the administrator adds them:
- bogus://oedipus.nostradamus.com
- bolo://lgm.cheshire.org
