Centered figures in org-mode LaTeX export

Question

When org-mode exports figures to LaTeX, the figure shows up left justified. Is there an easy way to have all the figures centered?

I want to avoid having to type #+ATTR_LATEX: :float t above each figure.

I would simply like each \includegraphics in the exported LaTeX code to be wrapped in a \begin{center} ... \end{center} block.

You can add advice to org-latex--inline-image:

(advice-add 'org-latex--inline-image :around
            (lambda (orig link info)
              (concat
               "\\begin{center}"
               (funcall orig link info)
               "\\end{center}")))

Note that this puts every inline image in \begin{center} ... \end{center}, even ones that are centered already by setting :float.
