I've at last found a way to post my newest Panoramio photos places other than Google Maps/Earth and Panoramio proper: the API widget! With this, I can add an iframe to any page and display my own photos from most newest to oldest. Right now I'm testing it out on the sidebar. It takes a little bit of time and effort to load the thing, but it seems to be working wonderfully anyway! See if THAT works for ya.
