hm OK.

I also most confess i didn´t do it the same way as the tutorial suggested

I used the rulers to do some guidelines and divided the images into 4 pieces (front, top , side and back) and i marked it with the marquee tool. Then i copied it and deleted, and i pasted in again, so it created a new layer.

Then i saved the layers individual and opened them 1 by 1.

THEN i copied the image on the layer. Pressed NEW and it automatically knew the proportions for the image and i pasted the copy into the new image.

When i have done that to the rest of them i fixed the proportions in height and side so the fitted together.

(sorry for the crappy English part
