I’ve known about Wikimedia Commons for a while, but a repository of over 21 million images is a little intimidating to tackle.  In addition, the search feature on the site can be frightening because you never know what you might find.  I’ve come across some disturbing photos.  (Read these two articles for some background: SignPost Commons Deletions and  How Wikimedia Commons became a massive amateur porn hub.)

I personally avoid the search on the main page, and now I narrow my search to the following pages:

• Picture of the Day
• Picture of the Year
• Featured Pictures
• Quality Images

Here are just a few of the amazing free images you can access and use in your deliverables:
