User Photo & RSS Feeds

Heya,

I was able to get the User Photo to appear in the primary feed.

eg. http://mysite.com/wordpress/feed

But not in category feeds.

eg. http://mysite.com/wordpress/feed/category/monkey/

Any ideas how to get the tag to work in this too?

I was using the following code tag in the feed-rss2.php file:

<userimg><?php userphoto_the_author_photo() ?></userimg>
