`org-create-formula-image-with-imagemagick' doesn't handle the case that
`org-latex-pdf-process' is set to a function.
To reproduce:
- set `org-latex-pdf-process' to a function
- (setq org-latex-create-formula-image-program 'imagemagick)
this makes preview fail
- set #+OPTIONS: latex:imagemagick => html export broken
However, just calling this function from
`org-create-formula-image-with-imagemagick' would not be a good idea.
How about adding a new variable `org-latex-formula-pdf-process'?

What about re-using the existing tool from "ox-latex.el"? What do you
think of the following patch?

Subject: [PATCH] Use `org-latex-compile' when processing formulas with
imagemagick
* lisp/ox-latex.el (org-latex-compile): Add an optional argument for
latex snippet previewing.
* lisp/org.el (org-create-formula-image-with-imagemagick): Use
`org-latex-compile' instead of rewriting it.

Very highly, this works perfectly. Thank you.
Unfortunatly, html export doesn't support imagemagick yet.
`org-html-latex-fragment' and `org-html-latex-environment' only handle
mathjax and dvipng. (I've added imagemagick to the dvipng case, and this
seems to work without any problems.)

Do you want to prepare a patch for that?
