attachmnet_fu can't keep original file image!

I am currently trying to create an application on RoR and I am using attachmne_fu plugin in order to handle image uploads. I have also install ImageScience to create some thumbnails for the images I upload

The problem is that I can upload images, but it resizes the original image to the thumbnail version. I don't know why. For example if I upload an image say IMG_2455.jpg, in the directory 0000/0002 I have 2 files: a) IMG_2455.jpg b) IMG_2455_thumb.jpg

but the original image is also resized! so i have two images of 125x83 dimensions. How can I keep the original image plus the thumbnail version ? Here is my code in my model

class Photo < ActiveRecord::Base

  belongs_to :user

  has_attachment :content_type => :image,                    :storage => :file_system,                    :size => 1.byte..12.megabytes,                    :thumbnails => { :thumb => '125x83>' },                    :path_prefix => "/public/photos/"

    validates_as_attachment

end

Any suggestions ??

It may have nothing to do with your situation, but I once had a similar experince when I forgot to install image magick...

but I think Ar's advice will probably work
