Title:
  Report crash with <image name="image_ref"/> tag

Status in OpenERP Server:
  New

Bug description:
  On server 6.0, revno 3342:

  If you have this kind of tag in a rml file:

  <images>
    <image name="test_image">iVBORw0KGgoA.....4035t7Em5s</image>
  </images>

  
  to define a constant image and call it later in your report via:

  <image name="test_image" width="2cm" height="1.5cm"/> for example

  the report crashes with:

  indeed, self.doc.images contains a dictionnary strings defining the images:
  self.doc.images = {'test_image': '\x89PNG\r\n\x1a\n\x ..... \x00IEND\xaeB`\x82', 'logo': '\x89PNG\r\n\x1a\n\x00\x00\x00\rIHDR\x00 .... \x00\x00\x00\x00IEND\xaeB`\x82'}

  The 'logo' image is an image of the company logo defined automatically
  and both images are string which do not have the 'read' attribute
  which kind of proves that 'str' is the correct format expected in this
  dictionnary....

  I'm not sure why it's there but it's clearly not supposed to be there:
  just change this line (see patch)
  image_data = self.doc.images[node.get('name')].read()
  into
  image_data = self.doc.images[node.get('name')]
