Adsense for feeds

[dilkebol]

Hello,
I am trying to start "adsense for feeds" for my 4images gallery .
Adsense Says as below :
If this is your first time setting up feeds with AdSense or FeedBurner, you'll need to burn a new feed first. Click the burn a new feed link, then enter your blog or feed URL. Some platforms may present you with a choice of feeds to use as the source; usually picking the Atom feed will work. You'll then be given a new URL for your feed which you should promote or redirect to in order to make sure all subscribers are seeing your enhanced feed.

When I click on "Burn New Feed", It is asking the Blog or Feed URL
Which is blog or feed url exactly.
i.e. http://www.xyz.com/4images/rss.php?action=images
or http://www.xyz.com/4images/rss.php?
or http://www.xyz.com/4images/rss.php

I entered
http://www.xyz.com/4images/rss.php?action=images
& created feed now my feed url is

http://feeds2.feedburner.com/thisisonlyexample

Is it done OK ?
If yes, then is it needed to replace default 4images RSS button(which links to http://www.xyz.com/4images/rss.php?action=images)when clicked ,or redirect it to 
http://feeds2.feedburner.com/thisisonlyexample

So that I can earn few cash with google. ?

Thanks in advance.

Got the Feedburner address but now the hard part is replacing the 4images RSS with this feed (that has the ads in it)

I guess the easy way is to replace each instance of {rss_url} with your Feedburner URL

<a href="{rss_url}"><img src="{template_url}/images/rss.gif" border="0" alt="{rss_title}" /></a>

But each page you are on has a different RSS feed. Eg Catagories has it's Feed, Details has it's feed, the home page has the it's feed etc...

So I guess the question is how to incorporate Feedburner into the script that builds the Feed?

Anyone know a way?
