Subject: Re: [tip] Export subfigures to LaTeX (and HTML)

This is an interesting use of links, in particular extending the
information in the description.

You might look at this
http://kitchingroup.cheme.cmu.edu/blog/2015/02/05/Extending-the-org-mode-link-syntax-with-attributes/
for another way to do that.

Check out this alternative approach all together that also uses a
special block.

http://kitchingroup.cheme.cmu.edu/blog/2016/01/17/Side-by-side-figures-in-org-mode-for-different-export-outputs/

I don't use either of these today, and they are old so who knows if they
still work, but they have some fun ideas in them.
