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="" ...> while it should
be <img src="" class="moz-txt-link-rfc2396E" href="file:///e:/dir/sth.png">"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-combine-plists (list :src (concat "file:///" source) :alt (if (string-match-p "^ltxpng/" source) (org-html-encode-plain-text (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.
