# What I did?

Removed unused arguments in favor of a splat. I did see in the photo.rb you are setting these arguments to things, but removed them in this pr to bring it to your attention.

I also updated the `.exists?` call to `.exist?` to comply with [Ruby 2.1](http://lisp.es/2014/05/05/ruby-2-1-deprecated-file-exists/).
