89925 Flirckr RSS Script Help

I have a script that takes this feed: [login to view URL] parses it and displays it on my site. The problem I am having is that it only displays the first 20 and on one page. I would like it to make a pagination link at the botto for multiple pages so the user has the ability to goto the next 20 results from that feed. I am not sure how to do this. I am hoping it is a quick fix and that I just need to change the feed url by adding a parameter that says "next 20" or something. If you can quickly assist me with this, please bid and we can move forward. Thanks all!
