Insert OBJ - problems!

I did some face (photographs) 2d to 3d with “looxis faceworx” a while ago (yes I know its old program). But now I have a problem. When importing the obj-file in Blender it smears out the background with it. (It does not appear as a head). Is there a easy way to fix this or how do I fix it?

Is there another program (free) that works with creating 2d to 3d? Or in blender?

it smears out the background with it.
What does this mean ?

If the object is imported very large then it may fall outside the clip start/end distances. If so scale the object down to a more reasonable size
