when i firstly saw it it felt like:
ughhh(jumped a bit the chair and poped eyes out and git my back to be vertical)
wtf?
thats all im not scary a lots of it...
lol i was showing it to my brother in all sound!!!
and he ranned when he just heard scream
They make me jump a little but I've become used to them now.

They are mroe rare now then they were, say, 5 years ago though.
I never get scared by screamers, only startled and then I laugh at myself for being naive, or I am disturbed. Most of the pictures used in screamers are not disturbing, and are clearly fake and poorly done in 5 minutes, just to scare you. So most of the time I'm fine with them, and besides I usually know when one is coming, there's always the telltale signs: turn up the volume, etc....
