right.  and welcome to the newsgroups.  you will want to read the
announcements newsgroup (all of the messages).  in them you will find
the proper useage for these groups, rules, etc.  this is a friendly way
of telling you that the image that you attached is in the wrong
newsgroup.  the povray.binaries.images group is where all images should
be posted.  commonly, if a message requires a picture for explaination,
you should put something similar to the following in your message:

"...<your problem>...

see the image i posted in p.b.i to see what i mean.

..."

by the way, no need to appologize for your english.  do your best to get
your point across, and we'll do our best to understand:)
