[Nmh-workers] Attaching graphics files

[norm]

I know how to attach a .tgz file. For example:
#application/octet-stream; \
type=tar; x-conversion=gzip; \
name=SoundShot.tgz /home/norm/Downloads/SoundShot.tgz

or a zip file. For example:
#application/zip; name=,a.zip /home/norm/Downloads/,a.zip

But how do I attach a .png file, for example, b.png?
or a  .jpg file,  for example, c.jpg?

Thank you all,
