Its hard to tell but with the second picture it almost looks like it could be a boy!
lakrav, like I told you before, there is no way of knowing the baby's gender from those images. Posting this question again won't change that. I'm sorry, I know you're anxious to know. Of the 6 images shown, the first four are of the baby's head/brain. The fifth is the baby's arm bone and the sixth is the thigh bone, which still doesn't reveal gender.
