An image is a link to an image file117 that does not have a description part, for example
If you wish to define a caption for the image (see Captions) and maybe a label for internal cross references (see Internal Links), make sure that the link is on a line by itself and precede it with ‘CAPTION’ and ‘NAME’ keywords as follows:
#+CAPTION: This is the caption for the next figure link (or table) #+NAME: fig:SED-HR4049 [[./img/a.jpg]]
Such images can be displayed within the buffer with the following command:
Toggle the inline display of linked images. When called with a
prefix argument, also display images that do have a link
description. You can ask for inline images to be displayed at
startup by configuring the variable
By default, Org mode displays inline images according to their
actual width. You can customize the displayed image width using
org-image-actual-width variable (globally) or
‘ORG-IMAGE-ACTUAL-WIDTH’ property (subtree-level)119.
Their value can be the following:
#+ATTR_HTML: :width 300px
and fall back on that number if none is found.
Inline images can also be displayed when cycling the folding state.
When custom option
org-cycle-inline-images-display is set, the
visible inline images under subtree will be displayed automatically.
What Emacs considers to be an
image depends on
org-startup-with-inline-images can be set within a buffer with the
‘STARTUP’ options ‘inlineimages’ and ‘noinlineimages’.
The width can be customized in Emacs >= 24.1, built with imagemagick support.
