12.6.5 Images in LaTeX export

Images that are linked to without a description part in the link, like ‘[[file:img.jpg]]’ or ‘[[./img.jpg]]’ will be inserted into the PDF output file resulting from LaTeX processing. Org will use an \includegraphics macro to insert the image. If you have specified a caption and/or a label as described in Images and tables, the figure will be wrapped into a figure environment and thus become a floating element. You can use an #+ATTR_LaTeX: line to specify various other options. You can ask org to export an image as a float without specifying a label or a caption by using the keyword float in this line. Various optional arguments to the \includegraphics macro can also be specified in this fashion. To modify the placement option of the floating environment, add something like ‘placement=[h!]’ to the attributes. It is to be noted this option can be used with tables as well1.

If you would like to let text flow around the image, add the word ‘wrap’ to the #+ATTR_LaTeX: line, which will make the figure occupy the left half of the page. To fine-tune, the placement field will be the set of additional arguments needed by the wrapfigure environment. Note that if you change the size of the image, you need to use compatible settings for \includegraphics and wrapfigure.

     #+CAPTION:    The black-body emission of the disk around HR 4049
     #+LABEL:      fig:SED-HR4049
     #+ATTR_LaTeX: width=5cm,angle=90
     [[./img/sed-hr4049.pdf]]
     
     #+ATTR_LaTeX: width=0.38\textwidth wrap placement={r}{0.4\textwidth}
     [[./img/hst.png]]

If you wish to include an image which spans multiple columns in a page, you can use the keyword multicolumn in the #+ATTR_LaTeX line. This will export the image wrapped in a figure* environment.

If you need references to a label created in this way, write ‘\ref{fig:SED-HR4049}’ just like in LaTeX.
