Here's some ideas on the LaTeX side; I don't use HTML nearly as much...

Do you have anything setting margins in your header? I can't stand the
default LaTeX margins, so every one of my article-style documents has
the following header:
#+latex_header: \usepackage[hmargin=2.5cm,vmargin=2.5cm]{geometry}

You can also ditch the title/date with this line:
#+BIND: org-latex-title-command ""

Note that to use this, you need the following in your config (or at
least to customize it to prompt the user if using #+bind is okay):
(setq org-export-allow-bind-keywords t)

Lastly, you can remove the footer (centered page number) with setting
an empty pagestyle:
\pagestyle{empty}

Putting it all together, see what you think of this result (I get a
pretty big image, with just the heading and the image).


#+begin_src example

#+options: toc:nil
#+latex_header: \usepackage[hmargin=2.5cm,vmargin=2.5cm]{geometry}
#+BIND: org-latex-title-command ""

\pagestyle{empty}


* test

#+begin_center
#+attr_latex: :width \textwidth
[[./tux.png]]
#+end_center

#+end_src

I downloaded this image as tux.png (same directory as the test file):

Hope that helps a bit,
John
