Would replacing

	  (kill-buffer obuf))))))

with

	  (setq buffer-file-name ofile)
	  (setq buffer-file-number onum)
	  (setq buffer-file-truename otrue)
	  (kill-buffer obuf))))))

fix that?

I never used 'find-alternate-file' and, after looking at its code for
the first time now, wouldn't touch it with a ten foot pole.  Using it in
'image-next-file' seems a very bad idea: Is there any guarantee that the
assumptions about which buffer is current hold when running things like
'kill-buffer-query-functions' or 'kill-buffer-hook' manually?
