What happens when you try? Do you get an error message?

You have chosen to use gnus-face-from-file and a JPEG - the
documentation says that it uses gnus-convert-image-to-face-command to
convert the image to PNG:

,----[ C-h v gnus-convert-image-to-face-command RET ]
| gnus-convert-image-to-face-command is a variable defined in ‘gnus-fun.el’.
| Its value is "convert -scale 48x48! %s -colors %d png:-"
| Command for converting an image to a Face.
| The command must take an image filename (first format argument
| "%s") and the number of colors (second format argument: "%d")
| as input.  The output must be the Face header data on stdout in
| PNG format.

Do you have ImageMagick installed on your machine (i.e. the package that
contains the "convert" command)?

To eliminate that potential source of problems you could save the image
as a PNG and use gnus-convert-png-to-face instead.

  Best regards,
