Hi,
While working on a presentation recently, I realised there was no easy
way to specify overlay specifications for images during beamer export.
Since this is already supported for lists, e.g. by adding
`#+attr_latex :overlay +-'. I was wondering if it is possible to add
this for images?
Something like this would be amazing:
#+attr_latex: :overlay 1 :width 0.9\textwidth
[[file:graphics/test.pdf]]
is exported as,
\includegraphics<1>[width=0.9\textwidth]{graphics/test.pdf}
What do you think?
PS: I noticed if I use #+attr_beamer: instead of #+attr_latex:,
the :options property is ignored, and :width is overwritten with
"0.9\linewidth". Is that intended

I am not sure about this problem, but clearly, your request of the overlay property need to use attr_beamer, not attr_latex.

I tried attr_latex because attr_beamer was overwriting everything. I
will investigate why attr_beamer is not working on a minimal instance
tomorrow.

I tested with a minimal setup. Same issue. The following:
#+attr_beamer: :overlay 1 :width 0.8\linewidth
[[file:bla.png]]
exports as,
\includegraphics[width=.9\linewidth]{bla.png}
Something is off.
Hope this helps,

Beamer back-end delegates external link handling to the LaTeX back-end
(see l. 723 in "ox-beamer.el"). The latter ignores everything about
Beamer and its attributes.
In most cases, you can specify an overlay attribute to a link using
export snippets (see "Beamer specific syntax" in section 12.5 of the
manual). But it requires adding contents to the link, which is
impossible for image links, as the must have no contents.
Therefore, in this case, Someone needs to copy image handling in
"ox-beamer.el" and add "ATTR_BEAMER" support there.
Regards,
