image border is opaque when viewing

[John Mitchell]

Jukka,

Thanks,

That worked but what surprised me is that is worked with IMAGEMODE of RGB.
I first tried it with PC256 which It did work as expected, but I was
pleasantly surprised to see it work with RGB since the documentation says
that it will not work with transparency.
