For anyone interested: The problem is there on a 1.5 G1, but not on a 2.1 Milestone/Droid. It might be the handset or the OS version, which i don't know.
The basics of the problem as far as I can see, is that the preview is returned in 2:3 (320:480), and the picture will be in 3:4 (1536x2048). Using a scaling-factor I can at least predict _how_ the picture will change. On the milestone/droid the numbers for the preview are 480:640, which is also 3/4, so the scaling issue is non-existent. I tried setting the preview to something 3:4, but as the allowed preview sizes are limited, and I can't get them with the API lvl 5 memberfunction, I didn't get very far (and haven't tried that much).
