Since Beamer back-end doesn't redefine how images are handled, you can
use the same properties as above, within an attr_latex keyword.

About special environments for plain lists, I'm unsure if this is a good
idea. AFAIK many don't support overlay specifications so it would lead
to errors when one provides both a special environment and an overlay,
i.e.:

--8<---------------cut here---------------start------------->8---
#+attr_beamer: :environment inparaenum :overlay "+-"
- item 1
- item 2
--8<---------------cut here---------------end--------------->8---

Also, Beamer has its own way to render standard lists (through themes)
and it could cause problems with foreign packages.

On the other hand, I can still make it easy for an user to shoot himself
in the foot: code-wise, it is cheap. What do you think?
