Cleans up the small images as well as the old script iterations

Long anticipated cleanup is here. To test: 

1. Check that everything you wanted there is still in the repo. 
2. Check that everything you did not want there is wiped out by this cleanup.
3. Think of anyone else who might want to keep or delete more stuff here, and check if this PR is complying with this.
