resort.send(:"image_#{file_count}=", photo_file)

- you can't build a variable name in ruby, if you want to do this, use
hashes
- :"" is a short form of "".intern (or "".to_sym)
- a.b can be written a.send(:b)
- when you write "a.b = 3", you call the method "b=" of the object a
with the argument 3.
