, i did that as you said
 ... i also discovered i could change pictures in those 2 already existing in the library objects (carpet and portrait) ---changing the settings in these objects i got a possibility to have vertical and a horizontal object with a stretching material on it...  but if i save these objects as new objects-then the material looses it's ability to stretch ......  
(other than that-- thus it's possible to have ONLY vertivally and horizontaly stretching objects)
----these 2 existing in the library objects have a different 3D script-->     (((IF gs_picture_name <> "" Then gs_picture_name,a,b,a Else)))))
i had a feeling that "<>" had something to do with stretching  .....but changing text in 3D script of new objects just gave me errors
