I don't like image-dired thumbnails, so I wrote this function to preview all
images in a directory in an Org buffer. I share it here, in case it is
useful to someone:

#+begin_src emacs-lisp
  (defun my-org-img-dired-preview ()
    (if (not (derived-mode-p 'dired-mode))
	(error "not in dired")
      (let* ((dir-name default-directory)
	     (buf (concat "*" dir-name "--images *")))
	(setq my-img-dired-list nil)
	  (goto-char (point-min))
	  (while (re-search-forward "\\.png\\|\\.jpg\\|\\.tif" nil t)
	    (let* ((img-path (dired-get-filename)))
	      (add-to-list 'my-img-dired-list img-path t))))
	(when (get-buffer buf)
	  (kill-buffer buf))
	(get-buffer-create buf)
	(set-buffer buf)
	(let ((img-list (mapconcat (lambda (el)
				     (let ((link (concat "[[file:" el "]]")))
	      (img-num (number-to-string
			(length my-img-dired-list))))
	  (insert (concat "* Images in " dir-name "\n\n"))
	  (insert (concat img-num " files:\n\n"))
	  (insert img-list)
	(pop-to-buffer buf)

  (with-eval-after-load 'dired
    (define-key dired-mode-map (kbd "P") 'my-org-img-dired-preview))

Best regards,

Juan Manuel
