Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Steps to reproduce:
1. $ emacs -Q &
2. Type the following expression and hit C-j in the *scratch* buffer.
(save-excursion
(goto-char (point-min))
(insert-image (create-image "splash.png"))
(insert ?\n))
3. Ditto.
(pos-visible-in-window-p (point-min) nil t)
Result:
The expected one is (0 0), but the actual one is (608 188). As far as
I tested, this happens at the first row (i.e., (window-start)) only
containing a single image. If you remove (insert ?\n) in the first
expression, then the result is (0 0) as expected.

Thanks for the quick fix. But it still returns a wrong value when an
image is not at the beginning of buffer but located at the first row:
(let ((p (point)))
(insert-image (create-image "splash.png"))
(insert ?\n)
(set-window-start nil p)
(pos-visible-in-window-p p nil t))
This returns (0 188) instead of (0 0). If we replace (insert ?\n)
with (insert ?a ?\n), then it returns (0 0) as expected.
