I'm trying to show an image when the target is there. 

 

I've tried to replace the 3d object by a plane with a texture of the image, but it doesn't works because, of course,  the image is moving when the marker moves and I would like it would be fix over the screen like it happens with GUItexture, for example.

 

I have five targets with five image to show.

 

Any idea?

 

Thank you!!
