custom image size into devise + facebook-omniauth

I'm using mongoid, rails 3.2.10 and omniauth on devise.. and trying to set up custom image_size of facebook profile image url

 config.omniauth :facebook , API_KEYS['facebook']['api_key'], API_KEYS['facebook']['api_secret'], :image_size => {:width => 100, :height => 100}

I configured as above.. but result is as below.. 

http://graph.facebook.com/636937446/picture?type=#<OmniAuth::Strategy::Options height=100 width=100>

so i checked out the facebook-omniauth Strategy.rb file. please tell what should i do.. 

  def image_url uid, options
    uri_class = options[:secure_image_url] ? URI::HTTPS : URI::HTTP
    url = uri_class.build({:host => 'graph.facebook.com', :path => "/#{uid}/picture"})

    query = if options[:image_size].is_a?(String)
      { :type => options[:image_size] }
    elsif options[:image_size].is_a?(Hash)
      options[:image_size]
    end
    url.query = Rack::Utils.build_query(query) if query

    url.to_s
  end

Hi I had the same problem. I actually edited my strategy.rb file, added my custom function and it worked perfect.

On line 39: change it to 'image' => image_url(uid,options),

Next edit the image_url method to something like this

  def image_url uid, options
    query = if options[:image_size].is_a?(String)
      { :type => options[:image_size] }
    elsif options[:image_size].is_a?(Hash)
      options[:image_size]
    end
    url = build_url("https://graph.facebook.com/","#{uid}/picture",query) if query

    url.to_s
  end

Here I call another method called "build url". So just after the image_url method define the "build url"

  def build_url(domain,path,params)
      return domain + "#{path}?".concat(params.collect { |k,v| "#{k}=#{CGI::escape(v.to_s)}" }.join('&')) if not params.nil?
  end

Save the file and thats it!! Hope it works for you!!!
