Yep ! Rip off that "Intel Inside" sticker off your computer and relpace it
with the "Ken Inside" sticker :)

Hmmm.... Do you really want me loose inside your computer ?

Alen,

I checked my preferences and selected plain text.  Hope it comes through
properly.  I have never used news groups before and had no idea this was
a consideration.

I rarely even touched upon the 'image_map {sys' before, although I seem to
recall trying to use a bitmap renamed to the *.sys extension and got various
results.  I'm sure however that I had tried the various combinations, like
sys type with bmp file and bmp type with sys file.  Nothing was ever
consistently right so I gave it up within a few days of trial and error.

  Scott, thanks for switching to text mode. Welcome to news.povray.org, by
the way.

  When you get a chance you might peruse the articles posted at the
povray.announce.frequently-asked-questions group, as many of these topics
come up quite often as fr... well, you know <grin>. Also of interest there
is Ken Tyler's Links Collection, which Ken updates quite frequently. You can
also find his links on the web at http://www.povray.org/links/.

Thank you Alan.  Being as new to this as I am I am now having to find
all the areas for support.  Thanks for your direction.

Two questions:
1) Is the bitmap uncompressed, or RLE compressed?

2) Are you using POV-Ray for Windows, or another version?
