Software Guide

Link Indication is a WordPress 2.3 through 2.9+ compatible plugin that applies CSS class attributes to the links (anchor tags) in your posts, pages, and optionally in your comments. Thereby you can indicate your links, e.g. by images, for characterizing your types of links.
Additionally, you can apply class attributes to special filename extensions, such as .pdf, .xls, .jpg, etc.

The plugin is applied at display time, not while a post is being saved. This means that this plugin can be integrated at any time, it will modify the rendering of existing posts and comments as soon as the plugin is enabled.

These URLs and filename extensions are fully configurable and you can add an unlimited number of rules.

Additional options:

• Add target="_blank" to all external hyperlinks
• Add rel="nofollow" to specific hyperlinks
• Display websnapr website preview thumbnails
  

Downloads

The download includes the following translations, thanks to the translators: German (not yet completed – anyone?), Italian and Belorussian.

Additionally, I have prepared several icons for download: images.zip (22k).

Also, check out my link collection for more icons.

Link Indication can be installed in 3 easy steps:

1. Decompress the .zip archive and upload the files into your plugins folder (typically located at /wp-content/plugins/).
2. Enable the plugin in the WordPress Plugins admin page.
3. Navigate to WordPress Administration » Settings » Link Indication and alter the settings.
