Subject: bug#37972: Emacs cannot deal with .webp suffix

Renaming .webp to .gif displays it, but also spews into stderr:

  Decoded /tmp/magick-6240. Dimensions: 320 x 214 . Format: lossy. Now saving...
  Saved file /tmp/magick-6240

Looks like debug info, should such fprintf be disabled?

Anyway, maybe these messages are less relevant since now we have
image-converter:

Thanks.  I tried now to enable image-use-external-converter and visit
a webp image, but it signals an error:

  Cannot display image: (Searching for program No such file or directory gm)

I don't know what this 'gm' is, never used it.  I have only 'convert'
installed.  Is it supported by image-converter?
