I want to open images in org-mode files using the system image viewer (like Eye of Gnome in Linux), is there such an addon that can do this with a command?

I figured out a way to do this, just add the following code to the configuration:
```lisp
(defun get-open-image-template ()
(cond ((eq system-type 'darwin) "open %s")
((eq system-type 'gnu/linux) "eog %s")
((eq system-type 'windows-nt) "start %s")
(t (error (format "Unsupported operating system: %s" system-type)))))
(defun open-image ()
(interactive)
(let ((image-path (org-element-property :path (org-element-context))))
(shell-command
(format (get-open-image-template) image-path))))
```
Restart emacs to make it take effect.
When you want to open an image using the system image viewer, just put the cursor on the image, and run `M-x open-image`.
P.S. The above code assumes that you've installed `Eye of Gnome` if you are in Linux. If you want to use other image viewers in Linux, change `eog` to the one you want.

There is the `org-file-apps` variable which takes care of this inside orgmode.
