[ynyaaa]

Evaluating the form below, the image object returned by find-image is
displayed as original size while the image object returend by create-image
is displayed twice the original size.

(let* ((image-scaling-factor 2)
       (img1 (find-image '((:file "gnus/gnus.xpm" :type xpm))))
       (f (image-property img1 :file))
       (img2 (create-image f 'xpm)))
  (insert-image img1)
  (insert ?\n)
  (insert-image img2))
