This is a site I stumbled across a while ago. It is a site of photos from numerous towns and pueblos of the Basque Country, at least the Spanish side. They have a pretty big list for Bizkaia, Nafarroa and Gipuzkoa, though the Araba section is a bit thin yet. They even have a set of photos from my dad’s home town of Munitibar. And the photos seem to be of good quality.
