Hi Derek,

In addition to Eric's response, if you wanted to have, say, text on the left side of the beamer frame and an image on the right, you can use beamer columns:

#+begin_src org
** Why do we care?                                                             
*** block                                             :B_ignoreheading:BMCOL:  
    :PROPERTIES:                                                               
    :BEAMER_env: ignoreheading                                                 
    :BEAMER_col: 0.35                                                          
    :END:                                                                      
+ \textcolor{green}{They are explosions!}                                      
+ Unique location for rp-process burning                                       
+ Flame propagation under extreme conditions                                   
+ \alert{Constrain EOS for dense matter}                                       
*** jim_figure                                        :B_ignoreheading:BMCOL:  
    :PROPERTIES:                                                               
    :BEAMER_env: ignoreheading                                                 
    :BEAMER_col: 0.8                                                           
    :END:                                                                      
#+ATTR_LaTeX: width=\textwidth                                                 
./images/jim_diagram2.png                                                      
\\ \tiny \flushright Lattimer, J.M., \textit{ApSS}, \textbf{308}, 371 (2007)
#+end_src

You can enter in the =:PROPERTIES: yourself, or you can hit =C-c C-b= on the line containing the particular block and select it as a column.  You can find more information here: http://orgmode.org/manual/Beamer-class-export.html

HTH,

Chris

Why not?  It would be helpful if you could post a minimal example of
what does not work.

not as such but you can do the following:

#+begin_src org
** a plain slide
#+attr_latex: width=[0.8\textwidth]
[[file:figure.png]]
#+end_src

and the figure should be included just fine.
