Putting LaTeX inside a figure environment on export

Putting LaTeX inside a figure environment on export

[William Denton]

Is there a way to get a line of LaTeX inside a figure environment when 
exporting from Org?

I've got a problem making an index of photographs where some of the photos are 
large and get floated to a different page, and the page number in the index is 
incorrect.

For example, let's say I have:

     #+caption: This is a large tree
     [[file:large_tree.jpg]]

When exported to LaTeX, this turns into:

    \begin{figure}[htbp]
    \centering
    \includegraphics[width=.9\linewidth]{large_tree.jpg}
    \caption{This is a large tree}
    \end{figure}

I want to use this to generate an entry in an index:

    \index[photos]{Tree}

Is there a way to get that *inside* the figure environment?  If it is, then the 
page number is correct.

If it's outside, then the index will point to the page where that line sits in 
the text, if you get what I mean.  If the figure would be in the middle of page 
15 but is so big it gets floated to page 16, then the index will say 15 (where 
the index command is), not 16 (where the image is).

Now that I've written this out I see I could make my own macro to do all this 
(I'd pass in filename, caption, and indexing information, and generate that 
LaTeX figure above with the index line inside), but is there a way built in to 
Org to insert LaTeX like this when exporting?  From what I see in the manual 
there isn't, one can only set attributes, not add a custom line, but I thought 
I'd ask.

Does the following work?

     #+caption: This is a large tree @@latex:\index[photos]{Tree}@@
     [[file:large_tree.jpg]]

Resulting LaTeX:

     \begin{figure}[htbp]
     \centering
     \includegraphics[width=.9\linewidth]{large_tree.jpg}
     \caption{This is a large tree \index[photos]{Tree}}
     \end{figure}
     \end{document}

By Jove, it does.  That's brilliant.  Thanks!
