This functionality certainly used to work (and was one of my main
reasons for using org-mime-htmlize).  There is a new error in the
`org-export-string' function when `org-export-with-LaTeX-fragments' is
set to "dvipng" which is causing export to fail.  To exercise this bug
run the following elisp snippet.

  (let ((org-export-with-LaTeX-fragments "dvipng"))
    (org-export-string "A fraction $\\frac{1}{2}$." 'html "/tmp/"))

Which throws the following error.

  org-format-latex: Unknown conversion type nil for latex fragments

Once this bug is fixed the use of LaTeX to generated inline images with
Org-mime should work once again.

Best,
