Cool. Can you please post a link to them.

How do I add image source? I find these on pinterest and they help back up my argument. I figured they would be self-explanatory. Should I link them to pinterest?

Yes please. Just include a link to the photos, some people do it at the very bottom of the post for all photos, some people do it under each photo individually.

Using the photos isnt a big deal, and improves your post, we just wanna make sure you link back to your source material on anything you didnt create.
