As I\'m using the Emacs Org mode as a research log, sometime I want to keep track of something via screenshot images, and I definitely don\'t want to save them. So I\'m wonderin

For Windows 10 users, I modified the answer provided by @assem to work with out-of-the-box tools:

(defun my-org-screenshot ()
  "Take a screenshot into a time stamped unique-named file in the
   same directory as the org-buffer and insert a link to this file."  
   (interactive)
   (setq filename
     (concat
       (make-temp-name
         (concat (buffer-file-name)
              "_"
              (format-time-string "%Y%m%d_%H%M%S_")) ) ".png"))
   (shell-command "snippingtool /clip")
   (shell-command (concat "powershell -command \"Add-Type -AssemblyName System.Windows.Forms;if ($([System.Windows.Forms.Clipboard]::ContainsImage())) {$image = [System.Windows.Forms.Clipboard]::GetImage();[System.Drawing.Bitmap]$image.Save('" filename "',[System.Drawing.Imaging.ImageFormat]::Png); Write-Output 'clipboard content saved as file'} else {Write-Output 'clipboard does not contain image data'}\""))
   (insert (concat "[[file:" filename "]]"))
   (org-display-inline-images))
