I want to have Org-mode file converted into HTML, htmlized HTML, and plain org 
file.
So I have following config:

,----
| (require 'htmlize)
| ;; (setq org-html-htmlize-output-type 'css)
|
| (defvar my-org-publish-directory "~/org-publish/")
|
| ;; projects definition
| (setq org-publish-project-alist
|       `(("blog-org"
|          :base-directory ,(concat org-directory "/Website/Blog/")
|          :base-extension "org"
|          :recursive t
|          :publishing-function (org-html-publish-to-html 
org-org-publish-to-org)
|          :publishing-directory ,(concat my-org-publish-directory "Blog/")
|          ....
|          )))
`----

I want to add a function into `:publishing-function` like
`htmlize-file`, but got arguments number error:

,----
| Publishing file /home/stardiviner/Org/Website/Blog/2016-04-22 22:54.org using 
‘htmlize-file’
| org-publish-file: Wrong number of arguments: (1 . 2), 3
`----

So how can I use htmlize in org-publish?

And I want to add a button "Show Org-mode version" button on every page.
How can I add this button in `:html-postamble` of org-publish to link to
current page's htmlized Org-mode page?
