Rails3 - Problem saving base64 image with paperclip?

This is similar to the problem posted here, but that solution doesn't work for me. Maybe it's because I'm not passing the data in correctly.

I'm pulling screenshots from Flash and displaying them on the page using Jquery:

   $SNAPSHOT_PREVIEW.attr("src","data:image/jpg;base64," + imgData);
   $HIDDEN_BASE64_STRING.val(imgData);

I had it nice and working where you could save the image to Rails in Flash, but Flash won't allow you invoke a post action without the user pressing a button for security reasons. Makes sense. Anyway, now I can't get Paperclip to save the image coming from the HTML form:

#(photo has_attached_file:image)
@photo = params[:photo]
data = StringIO.new(Base64.decode64(params[:base64_string]))
data.class.class_eval { attr_accessor :original_filename, :content_type }
data.original_filename = "screenshots.jpg"
data.content_type = "image/jpg"
@photo.image = data

Yields the error:

NoMethodError (undefined method `image=' for #<ActiveSupport::HashWithIndifferentAccess:0x8c2e420>):

How do I need to finesse the base64 image data into a paperclip attachment?

For bonus points, do I need the hidden field to pass the data or is there a clever, browser compatible way to use the image src as a form value?

You have the code:

@photo = params[:photo]

params is just a hash, so later, when you call @photo.image, Rails bugs out. Perhaps you want:

@photo = Photo.new(params[:photo])

instead?
