Hi Mano. It doesn't really matter whether or not your "picture" model  
interacts with a database. Simply use mocks and stubs when speccing  
#scan , and you'll be good. For example:

describe '#scan' do
   describe 'receives a POST request' do
     before :each do
       # mock an Image instance
       # stub Image#new
     end

     it 'should create a new Image'
     it "should set the new image's 'blob' attribute"
     it 'should save the new image'
   end

   describe 'receives a non-POST request' do
     # stuff here
   end
end

Obviously you have to fill in the contents of those #it blocks, but  
that's really all you need.
