You could also make a link = do that.

Huh.=C2=A0 This wasn&#= 39;t at all what I was thinking but it may be a much better way than I'= d htought of.=C2=A0

A link seems like it woul= d be a great solution, especially if I could figure out how to get the :fol= low function to open an individual ~src~ path. Would you use "looking-= at" to get the right candidate, or can you think of a way to get compl= etion candidates for a function that opens the file? I'm looking at you= r eamples in https://kitchingroup.cheme.cm= u.edu/blog/2016/11/04/New-link-features-in-org-9 but can't quite fo= llow the code.

Thank so mjch for this really inter= esting solution.

I am trying ot figure out if I can c= reate a simplified syntax for a particular special block in a derived HTML = exporter.=C2=A0

I'm trying to produce HTM= L like this:

<div class=3D"r-stack>
=
  <img data-fragment=3D"fade-out" src=3D"...."/>
  <img data-fragment=3D"fade-in" src=3D"..."/>
=
</div>


The derived backend =
(org-re-reveal) already has an 
#+ATTR_REVEAL that an make the data-fr=
agment attributes, so it's not hard to produce
 the desired outpu:
#+begin_r-stack
#+ATTR_REVEAL: :frag appear
[=
[imglink1]]
#+ATTR_REVEAL: =
:frag appear
[=
[imglink2]]
#=
+end_r-stack


However, I'd really like to add a less verbose syntax, like t=
his:

#+begin_r-stack :frag (appear appear)
[=
[imglink1]]
[=
[imglink2]]
#=
+end_r-stack

My question is: will the exporter preserve information from these hea=
der-like arguments, and is 
there a mechanism I can use in a custom ~spe=
cial-block-function~ to make use of htem?

Thanks for your help as =
always!
