World Images, according to its site, is a “database that provides access to the California State University IMAGE Project. It contains almost 75,000 images, is global in coverage and includes all areas of visual imagery. WorldImages is accessible anywhere and its images may be freely used for non-profit educational purposes.”
I’ve added it to The Best Online Sources For Images.
Thanks to the The Center For Applied Second Language Studies‘ excellent free weekly e-bulletin InterCom for the tip. It’s on The Best Ways To Keep-Up With Current ELL/ESL/EFL News & Research list. I’d encourage readers to it.
