Hey... I'm not starting a new thread bc this probably is so simple and is also related to developers "against" maemo.org (lol).
I have two apps so far, one of them automatically got a screenshot there while the other is without one. How could the author submit a screenshot?

@jlu:
My apps had the same downloads explosion (~380>~11967 and ~450-> 9973 )! I believe they added downloads from app manager to the number.
