First of all, it depends on what version of org you are using.  Assuming
you are using a recent version, your syntax here is wrong; it should be:

  #+ATTR_LATEX: :width 0.1\textwidth

Secondly, the attribute will only apply to the first image (I believe)
so you will need to repeat the attribute setting.  Actually, it may
apply only to the item and not the image.  You many need to do something
like this:

#+begin_src org
  -
    ,#+ATTR_LATEX: :width 0.1\textwidth :center nil
    [[./images/debian.png]]
  - 
    ,#+ATTR_LATEX: :width 0.1\textwidth :center nil
    [[./images/redhat.png]]

#+end_src

If you are using an older version of org, I highly recommend upgrading
especially if you intend to use beamer.
