Hi,

Is it possible to stop rendered (with C-c C-x C-l) formulas from
reverting back to LaTeX source in case of:

1. Pressing C-c C-x C-l to render a formula in other part of the
document. All other formulas revert to LaTeX code in that case.
2. Pressing C-c C-c to, for instance, evaluate some babel block. In
this particular case it looks like I need to reassign the C-c C-c
keybinding used to remove the images, but I don't know which function
is called to achieve that.

In the both cases the images get replaced by the LaTeX source. What I
want is to keep the images at all times, and revert only an image I
want to edit LaTeX code for.

Thanks
Alex

I don't think either is possible with the current code. 

Re. item 1: You can selectively render formulas by limiting the region
to a subtree, so it should be possible to do what you want by adding a
couple of functions and coming up with a decent user interface.

Re. item 2: this is done unconditionally in the function
org-ctrl-c-ctrl-c (in file lisp/org.el) and although I don't know the
reason, there probably is one and it's probably important[fn:1], so you
should proceed with caution. If you want to experiment, I'd suggest you
start by commenting out the >>>>> marked line <<<<< below in
org-ctrl-c-ctrl-c and testing extensively to see what breaks:

,----
| ...

|   `org-confirm-babel-evaluate' can be used to control prompting

|   inhibited by setting `org-babel-no-eval-on-ctrl-c-ctrl-c'."

|       (and (boundp 'org-clock-overlays) (org-clock-remove-overlays))
|       (org-remove-occur-highlights)
| >>>>> (org-remove-latex-fragment-image-overlays) <<<<<
|       (message "Temporary highlights/overlays removed from current buffer"))

`----

Cheers,
Nick

Footnotes:

[fn:1] I suspect that it's a necessary precondition for some of the
       *many* things that this function does, but I don't know for sure.

Would it be possible to use the more sophisticated Preview LaTeX of
AUCTeX? IMO it has a nicer way of dealing with previews.

Do you mean: "replace the org preview mechanism with the preview-latex
preview mechanism"? or "turn on auctex mode/preview-latex in addition to
org-mode in the org file"? or perhaps "export to latex and then use
preview-latex on the latex file"?

In either of the first two cases, my answer is "I don't know". IIRC,
there was some discussion of the former in this list a long time
ago. The second one sound easier (there are a couple of different ways
to turn on multiple major modes - see
e.g. http://www.emacswiki.org/emacs/MultipleModes) but I don't know how
conflicts between them are managed (and I imagine there will be plenty
of those), or what other problems might arise; it might be worth trying
though.

The third one is not as convenient as the other two might be, but it
exists *now* and does not require anything extra: bird in the hand and
all that.

Cheers,
Nick

Either (i) or (ii), I guess.  I just checked.  It seems preview-latex
needs a tex file to work as it call filename.tex.  Of course, a file
could be generated upon request.  I don't know whether one could weave
them back together afterwards. 

Which I mostly miss from preview-latex is the possibility to `walk into'
generated pictures, and to easily regenerate stuff.
