This is so easy to do and a great advantage of adding RSS feeds to each category is that it will display a single category feed when viewing a specific category. This makes it easier for readers to subscribe to their favourite category and it also makes it easier to submit your RSS feeds to directories and bookmarking sites.

To see a demo you can take a look at my sidebar and see the way I  have added RSS icons to each of my categories. Just scroll down the page and you will see the categories on the rightside of the page. If you want the same thing then follow these easy steps:

1. Login to your Wordpress administration panel
2. Select Presentation ->Theme Editor from the navigation menu
3. On the Theme Editor page, you will see a list of “theme files” to the right of the page. Select the “sidebar template” (sidebar.php).
4. Find the code thats looks similiar to this
   <?php wp_list_cats(’sort_column=name&optioncount=1′); ?>
   Overwrite this line of code with the following
   <?php wp_list_cats(’orderby=id&show_count=1&hierarchical=1&feed_image=/images/rss.gif’); ?>
5. Save

Insert the RSS Image

1. Grab an RSS image from the internet and resize to 10 pixels (height and width)
2. Upload the RSS image to you image folder, i.e. www.domain.com/images/

That’s it your done!
