I modified the latex2png-move2pubdir function to this (with an extra
line to move the png file to the output-dir ) . Sorry, I am still
learning how to contribute to the project, and am not sure how to
submit a "patch".

(defun latex2png-move2pubdir (file prefix pubdir)
  "Move FILE to the PUBDIR folder.

This is done so that the resulting images do not clutter your
main publishing directory.

Old files with PREFIX in the name are deleted."
  (if (and (file-exists-p file)
           (file-directory-p pubdir))
      (progn
        (let ((files (file-expand-wildcards (concat pubdir prefix "_*") t)))
          (copy-file file (concat pubdir (file-name-nondirectory file)) t)
          (copy-file file (concat output-dir "/latex/"
(file-name-nondirectory file)) t)
          (delete-file file)
          (concat "./latex/" (file-name-nondirectory file))))
    (message "The latex folder does not exist!")))

Should a subdirectory of images in the wiki directory be moved to the
publishing directory ? Is that a feature of muse-mode publishing ?
