Another great breakdown @simgirl!

One tip from me, so your head stops hurting!

On google image search I first search for my goal, lets say I am looking for friends.

Then I can click on settings, and go down to advanced search. This will take us to a window like this:

If we scroll down to usage rights, we can select from several options. I consider that we are not making 'money' here, at least not money as defined by the government, instead we are using and sharing! Once I pick free to use and share, I click advanced search.

Here we can see that we get a different set of pictures, mostly not showing the faces of any of the television friends!

Hopefully this guide to finding friends will help you ;p
