[junma]

 I use gnuemacs+emacs-wiki in XP,
home=d:/emacs
the configration about latex2png in .emacs is:
    (require 'emacs-wiki)
    (load "~/elisp/latex2png.el")

    (push '("latex" t t t gs-latex-tag) emacs-wiki-markup-tags)
    (setq gs-latex2png-scale-factor 2.5)       

    (setq emacs-wiki-maintainer "mailto:address@hidden";)
    (setq emacs-wiki-directories '("d:/emacs/WiKi/draft"))
    (setq emacs-wiki-publishing-directory "d:/emacs/WiKi/publish")


when use <latex> $x^{2}=y^{2}$ </latex> to get *.png file,it's always
wrong; the message is:
       Failed to create dvi file c:/DOCUME~1/JunMa/LOCALS~1/Temp/_47521900
