Woophy has thousands of student-appropriate photographs from throughout the world. They are easy to locate just by typing in key words.
I’ve placed the link on my Geography page under the Sites That Cover Many Areas section. It’s near the bottom of that category and I’ve entitled it “Geography Photos.”
I learned about this site from a post in Education With Technology blog. That same post lists other links that have more geography photos. I just thought Woophy was the best and easiest for English Language Learners.
