How to resize images in org-mode

Question

Is there a general way to define the size, in percent or pixels, for an image that is linked in org-mode?

Say I have the following link in my .org file:

[[~/images/example.jpg]]

This JPG is way too large, so if I export it to HTML or LaTeX or open it in org-mode with C-c C-o i will only see a fraction of the image.

Answer 1

As of Org 8.0, "Attribute lines now take plists" :

#+attr_html: :width 100px
#+attr_latex: :width 100px
[[~/images/example.jpg]]

Answer 2

As per Jacobo's comment, add the following to your init.el file:

(setq org-image-actual-width nil)

Then in org-mode, you can use this for inline previews of JPGs and PNGs. Doesn't appear to work for SVGs (no idea why)

#+ATTR_ORG: :width 100
[[~/images/example.jpg]]

and if you want to size this for both inline previews and html output:

#+ATTR_HTML: width="100px"
#+ATTR_ORG: :width 100
[[~/images/example.jpg]]

Answer 3

#+ATTR_HTML: width="100px"
[[~/images/example.jpg]]

This is a sample on how to resize an image using percentages (Org mode version 9.0.5):

#+CAPTION: Weight space                                                                                                                                     
#+ATTR_HTML: :alt neural network :title Neural network representation :align right                                                                          
#+ATTR_HTML: :width 50% :height 50%

For LaTeX, to remove the default width=.9\linewidth, set the org-latex-image-default-width to empty string. By this way, the image will have its natural size.

To do that on the fly use the set-variable emacs command. Or to set this variable permanently, add the following line in your init.el : (setq org-latex-image-default-width "")
