Don't you use xdg-open or the like[1] for the external viewer?
It starts the real viewer program as a background job and quits
immediately.  So, Emacs will recognize that the viewer finishes
and the temporary image file gets unnecessary, and tries to delete
it.  After the viewer finishes, emacs-w3m makes Emacs wait for 1
second before deleting the file.  It might be too short, though.
Could you try increasing the timer value?  Here it is:

(defun w3m-external-view-file (command file url arguments)
[...]
		   (run-at-time 1 nil

If it needs to be a long time, it would be necessary to schedule
deleting the temp files by `kill-emacs-hook' as well.
