For "east up" I think the world file might look something like:

0.0
0.5
0.5
0.0
top-left-x
top-left-y

You might need to fiddle around with the orientation a bit to get it
right.

Best regards,

But presumable the pixel sizes (1st & 4th) would not be zero?

Zoltan,

For east-up or west-up I believe that the 1st and 4th elements in the
world file *should* be zero and the 2nd and 3rd will be the pixel size
though I may be mixed up about the signs.  More detail on the meaning
of the world file is available at:

Best regards,
