When exporting an org file containing latex fragments with option

#+OPTIONS: tex:dvipng

in the html file the png image src attribute's value is not a valid URI. <img src="e:/dir/sth.png" ...>  while it should be <img src="file:///e:/dir/sth.png" ...>  for the browser to work. In my config I have  (setq org-preview-latex-image-directory "E:/tmp/ltximg/") so that all images are created in a single directory and don't clutter my org file directory.

I fixed this issue for me by modifying `org-html--format-image' function of ox-html.el file as follow:

(defun org-html--format-image (source attributes info)
  "Return \"img\" tag with given SOURCE and ATTRIBUTES.
SOURCE is a string specifying the location of the image.
ATTRIBUTES is a plist, as returned by
`org-export-read-attribute'.  INFO is a plist used as
a communication channel."
  (if (string= "svg" (file-name-extension source))
      (org-html--svg-image source attributes info)
    (org-html-close-tag
     "img"
     (org-html--make-attribute-string

		       (org-find-text-property-in-string 'org-latex-src source))
		    (file-name-nondirectory source)))
       attributes))
     info)))

I just changed (list :src source ...) to (list :src (concat "file:///" source).

I don't know if it is an acceptable way or it further causes bugs in other places.
Hope that this will find the proper way and fix it.
