+I following installation and configuration instructions at `http://ikiwiki.info/plugins/teximg/`
+
+But I get
+
+    [[!teximg Error: missing tex code]]
+
+for code
+
+    [[!teximg $$\sin (x)$$]]
+
+On server I do have `texlive`, `dvips`, `convert` installed ready. My configuration looks like
+
+        # teximg_dvipng => 1,   # use dvipng                                                                                                                
+        teximg_dvipng => 0, # use dvips and convert
