Having a very brief look through the Flickr API I would suggest you might need to do something like the following:
- request recent public photos using
flickr.panda.getPhotos
- loop through and plot your photos on the map using the lat/long values returned in the results.
I don't think you will be able to request all public photos (other than maybe your own).
An example result from flickr.panda.getPhotos
looks like this:
<?xml version="1.0" encoding="utf-8" ?>
