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)
        (list :src (concat "file:///" source)
	     :alt (if (string-match-p "^ltxpng/" source)
		       (org-find-text-property-in-string 'org-latex-src source))
		    (file-name-nondirectory source)))

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

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.

* Vector Subspace

  such that $S$ itself is a vector space. (i.e. it must be closed
  under addition, and scaling and thus also include $0$)
