I indeed implemented all same behavior like `org-latex-preview' in new
`org-toggle-inline-images'.

For (1), org-latex-preview has a `cond' logic to toggle preview in
region. Here is the code from `org-latex-preview'.

((use-region-p)
    (message "Creating LaTeX previews in region...")
    (org--latex-preview-region (region-beginning) (region-end))
    (message "Creating LaTeX previews in region... done."))

+

;; Clear current section.
   ((equal arg '(4))
    (org-clear-latex-preview
     (if (use-region-p)
         (region-beginning)
       (if (org-before-first-heading-p) (point-min)
         (save-excursion
	   (org-with-limited-levels (org-back-to-heading t) (point)))))
     (if (use-region-p)
         (region-end)
       (org-with-limited-levels (org-entry-end-position)))))

And I also implement the toggle inline images in region logic in
`org-toggle-inline-images' as bellowing:

;; Display region selected inline images.
   ((use-region-p)
    (message "Displaying inline images in region...")
    (org-display-inline-images include-linked t (region-beginning) (region-end))
    (message "Displaying inline images in region... done."))

+

;; Clear current section.
   ((equal arg '(4))
    (org-clear-latex-preview
     (if (use-region-p)
         (region-beginning)
       (if (org-before-first-heading-p) (point-min)
         (save-excursion
	   (org-with-limited-levels (org-back-to-heading t) (point)))))
     (if (use-region-p)
         (region-end)
       (org-with-limited-levels (org-entry-end-position)))))

------------------------------------------------------------------------

For (2), It's working. The code passed the parameter `include-linked' to
`org-display-inline-images'. So they works in any case of [C-u] prefix.

Maybe you want to eval the patch code to test.
