getting all attachments, getting images

[meOme]

Hi!
How can I get a list of all mails with an attachment in notmuch?
I tried:
notmuch search attachment:'*'
but that doesn't seem to work, as the result is lesser than e.g.:
notmuch search attachment:jpg
in my case.
One more question:
How can i find all messages with an image as attachment?
Something like:
notmuch search attachment:image
which should result in jpg+png+... images, so the Content-Type: image/*
Is that possible in notmuch?
Thanks a lot again!
