There seems to be a lot of conflicting advice being shouted out (and some where people havnt even looked at the pic!)
Lots of people suggest putting the tops level, which is fine and looks like they are in the pic (maybe a bit pointing up but i think thats because of the angle of the photo). However, with the bars you have this puts the very bottom of the drops at a quite hideous angle.
You could put the bottom of the drops level but this will give the tops (or ramps as they are often called) a very downwards slant towards the lever, probably a bit uncomfortable for a newbie. Worth noting that those bars are designed to be used like that.
Essentially then, with those bars, your kind of stuck with choosing one or the other, personally i cant stand ergo bars like yours and switch to the more round bars as shown in the pics other people have posted. Whatever you do you'll prob want to move the brake levers, aim for getting the tops of the hoods level (the face of brake lever should be vertical) as a good starting point, but expect to be moving them a few times until your happy.
Good luck.
