Caching my Flickr photos

Hi,

I wonder if it is possible to cache my flickr pictures fetched with
the API (rflickr)?

I want to show my albums first, and then when I click an album I want
to do a render partial and show the photos of that particular album.
This works just fine. But a bit slow, because I always have to contact
Flickr.

Is there a way I can cache both albums and pictures?

Thnx!
