This line return t for both windows, but the whole when clause return
nil for one of the 2 windows.
I will try to debug more (hard because i have to quit emacs at each
time) later.

Here the relevant piece of code:

--8<---------------cut here---------------start------------->8---
;; An image file and it is the second hit on C-z,
;; show the file in `image-dired'.
((string-match (image-file-name-regexp) candidate)
 (when (buffer-live-p image-dired-display-image-buffer)
   (kill-buffer image-dired-display-image-buffer))
 (image-dired-display-image candidate)
 (message nil)
 ;(switch-to-buffer image-dired-display-image-buffer) <<<< [1] 
 (display-buffer image-dired-display-image-buffer)    <<<< [2]
 (with-current-buffer image-dired-display-image-buffer
   (let ((exif-data (anything-ff-exif-data candidate)))
     (image-dired-update-property 'help-echo exif-data))))

--8<---------------cut here---------------end--------------->8---
See Capture-Emacs.png for [2]
See Capture-Emacs-1.png for [1]

Where [1] is what is expected.

After [2] C-g do nothing and i must quit Emacs.
