The JPF Add to Yahoo plugin is a social bookmarking plugin that allows users to submit posts to Yahoo.com. If the user is already logged in to Yahoo, it automatically submits the posts URL and Title. The download includes two files, jpf_yahoo.php is the plugin, copy it to your Wordpress plugins folder and activate the plugin in your plugin manager, and yahoo.gif, an optional icon that can be used as part of your link.

Once the plugin is activated, include the following somewhere in ‘the loop’, most likely in one of your templates:
<?php jpf_yahoo(); ?>
This will display text that says ‘Add to Yahoo’ which links to the Yahoo.com submit page. If you want more control over the appearance, you can add a few parameters:
<?php jpf_yahoo({before}, {Link Text}, {after}); ?>
Here’s how I use it. I first copy the included yahoo.gif file to my image folder, in my case /wp-images/icons. I then include the following in my template:
<?php jpf_yahoo(”,’<img src=”/wp-images/icons/yahoo.gif” alt=”Yahoo” /> Add to Yahoo’,”); ?>
That’s it!
