Anyone who knows me knows I loves me some Creative Commons photos. They’re free, they’re pretty and they’re good for the life of your blog or website.
Somehow, though, I didn’t know about Creative Commons Search until just recently (thanks, @rcwant2be). The site, which “is not a search engine,” is a search engine for search engines that lets you look for images under conditions such as “I want something that I can … use for commercial purposes.” Is a fast way to look in multiple places at once for whatever it is you need.
As the site says, you should always check the actual license for the photo (or whatever you’re searching for) at the link.
