Added images to the repo

Image links were busted, added to the repo to see if I can link to them
successfully.
Update README.md

Updated the images to link to the raw files in the repo.
Merge pull request #5 from joshtronic/master

Fixed images by putting them in the repo. From my understanding it worked before on the main repo, but not for forks. Maybe we can now link to them even relatively in Readme.md
