Okay, I was able to figure out the first four values now!
The data has a resolution of 1km/px so I want something like
1000.00
0.00
0.00
-1000.00
there, is that correct?

The only thing I'm unsure about are the last two values.
It is an image of the whole world, so shouldn't that be something  
like -180.00 for the first value and 90.00 for the last?

When using these values gdalinfo gives me a strange output for the  
offsets which can't be correct.

Sorry to bother you again.
