title: omniauth facebook doesn't show image
body: <p>I am using the omniauth-facebook gem and it all works perfectly, except the profile picture won't show; instead of showing the picture when I put in the code <code>image_tag current_user.image.to_s</code> or <code>image_tag current_user.image</code> it shows text (saying Picture?type=normal, square, large) instead of the picture itself.</p>
  
  <p>omniauth.rb</p>
  
  <pre><code>Rails.application.config.middleware.use OmniAuth::Builder do
  provider :developer unless Rails.env.production?
  provider :facebook, '166053726877178', 'df9249e9b70ef047e7a9456c7ebf9632',
  :image_size =&gt; 'square'
  end
  </code></pre>
  
  <p>and user.rb</p>
  
  <pre><code>class User &lt; ActiveRecord::Base
    attr_accessible :email, :image, :name, :nickname, :provider, :uid
    has_many :pictures
  
  def self.create_with_omniauth(auth)
    create! do |user|
      user.provider = auth["provider"]
      user.uid = auth["uid"]
      user.name = auth["info"]["name"]
      user.email = auth["info"]["email"]
      user.nickname = user.email.split("@").first
      user.image = auth["info"]["image"]
    end
  end
  
  acts_as_voter
  end
  </code></pre>
  
  <p>thing is, with this type of code it worked on a previous app, but it won't work here.
  thanks in advance</p>
