sending a file only with no comment attached

slacker -c cloudops-pagerduty -f ~/Downloads/image.png
does not work
echo | slacker -c cloudops-pagerduty -f ~/Downloads/emayssat.png
does but there are 2 entries in the slack stream.
why does a file upload require a comment?
I don't think this should be a requirement.
