Same here, but I was wondering: the function that Leo fingers looks like this

,----
| (defun org-export-html-preprocess (parameters)
|   ;; Convert LaTeX fragments to images
|   (when (plist-get parameters :LaTeX-fragments)
|     (org-format-latex
|      (concat "ltxpng/" (file-name-sans-extension
| 			(file-name-nondirectory
| 			 org-current-export-file)))
|      org-current-export-dir nil "Creating LaTeX image %s"))
|   (message "Exporting..."))
`----

and when I step through it, the when expression evaluates to nil, so the
whole thing is skipped. So it may be some setting in Leo's setup or maybe
something is missing from the fragment, that would make that expression
non-nil. So my question is:

What do I have to do to make

     (plist-get parameters :LaTeX-fragments)

non-nil?
