Don't do that, you will regret it. Associations and the rails magic
they give you are one of the fundamentals of rails. For example,
having setup the associations you will be able to get the albums for a
user using

current_user.albums

and to get the images for a user for a particular album something like
current_user.albums.where( category: "the category").images

The code you will need to write to do the same using a hash will be
much more complex
