Then repeatedly use 'i +' till the image is taller than the window. The image can be scrolled using mouse wheel. Now do M-x pixel-scroll-precision-mode After this attempting to scroll the image will set the vscroll to 0 and then image can't be scrolled at all. >From some investigation it seems like this behavior is not specific to image-mode. Another way to reproduce the behavior is to evaluate the following lisp code, (let* ((win (display-buffer (get-buffer-create "image-pixel-precision-test"))) (height (* (window-text-height win t) 2)) (file "path/to/image")) (select-window win) (erase-buffer) (insert-image (create-image file nil nil)) (goto-char 1) (pixel-scroll-precision-mode) nil) This image thus displayed can not be scrolled. However if the code above is slightly modified to insert a new line after the image, scrolling can be done normally, i.e. (let* ((win (display-buffer (get-buffer-create "image-pixel-precision-test"))) (height (* (window-text-height win t) 2)) (file "path/to/image")) (select-window win) (erase-buffer) (insert-image (create-image file nil nil)) (insert "\n") (goto-char 1) (pixel-scroll-precision-mode) nil) produces an image that can be scrolled. Inserting a newline after the text covered by the text property holding the image also fixes the problem in 'image-mode' but that doesn't seem like the right fix to me.
