Why is that a problem? The default Emacs scrolling commands don't guarantee smooth constant-rate scrolling, they guarantee only that you get to see all the portions of the image, without missing any. So when you get to the end of the image, there's a heuristic that decides whether we can scroll past the image, and that is what you see. I see no bug here.

On my machine, I don't get "End of buffer" error. I tested three
different ways in the following snippet
(with-current-buffer (get-buffer-create "*test-scroll-image*")
(erase-buffer)
(insert-image (create-image "splash.png" nil nil
;; Scale the image more if it doesn't take up the whole window.
:scale 5))
(goto-char (point-max))
(pixel-scroll-precision-mode -1) ; Ensure mouse wheel scroll up and down works
(pop-to-buffer (current-buffer)))
1. "M-: (scroll-up) RET" (repeatedly)
2. C-v (repeatedly)
3. <wheel-down> (repeatedly)
With all three methods, at first Emacs gradually scrolls the image, but
then when I reach the bottom of the image, the image disappears entirely
as Emacs scrolls past it all at once.

You're right. This is not a problem in practice. When point is before
the image, both C-v and <wheel-down> produce the same behavior as above.

If this is unexpected, please tell why. > Even more unexpectedly, when point is before the image, running > `scroll-up' repeatedly eventually scrolls back to the top of the image: > > (with-current-buffer (get-buffer-create "*test-scroll-image*") > (erase-buffer) > (insert-image (create-image "splash.png" nil nil :scale 5)) > (goto-char (point-min)) > (pop-to-buffer (current-buffer))) I do see this, but why is that a problem? You supposed to use scroll-up-command instead, which handles these marginal cases much better. scroll-up itself is not smart enough to avoid the perceived "scroll back to top", which is actually caused by the fact that we zero out window-vscroll (which is how we handle scrolling past large images).

When the image at point is larger than the current window and there is
no content after the image, interactively scrolling down (with the
scroll-up command) unexpectedly scrolls past the image to blankness.
Test this by evaluating the following snippet then interactively running
`scroll-up' repeatedly:
(with-current-buffer (get-buffer-create "*test-scroll-image*")
(erase-buffer)
(insert-image (create-image "splash.png" nil nil
;; Scale the image more if it doesn't take up the whole window.
:scale 5))
(goto-char (point-max))
(pop-to-buffer (current-buffer)))
Even more unexpectedly, when point is before the image, running
`scroll-up' repeatedly eventually scrolls back to the top of the image:
(with-current-buffer (get-buffer-create "*test-scroll-image*")
(erase-buffer)
(insert-image (create-image "splash.png" nil nil :scale 5))
(goto-char (point-min))
(pop-to-buffer (current-buffer)))
Non-interactively, scroll-up scrolls the page down to the very bottom of
the image. IMO this is the expected behavior:
(with-current-buffer (get-buffer-create "*test-scroll-image*")
(erase-buffer)
(insert-image (create-image "splash.png" nil nil :scale 5))
(pop-to-buffer (current-buffer))
(scroll-up 999))
Thank you for your help!!
