This is only correct for IE 4 for Windows, IE 4 for Mac OS does not support
it at all (but IE 5 does).

Woohoo! - thanks:)
The updated win32 3.1g interface is the icing on the cake:)

This doesn't bother me at all, and serves them right that such a popular
graphics program (or at least a popular patch of one;) should drop their
format because of their ridiculous legal issues.

The banner on top of that Unisys page is a gif image.  If Unisys has not
licensed itself, it will have to sue itself!  ;)

I have used Paintshop Pro to look at them, but only after 
changing *.pot to *.gif

GraphicConverter(a Mac image editor) will open them, but it seems(at 
first glance, anyway) to treat them as ordinary GIF images.

If I am asking an old question, please forgive me.

How much MegaPOV is going to look like Povray 3.5? I mean, if I write MegaPOV
code today I am going to throw out everything or we can expect minor
modifications which can be quickly performed?

The obvious reason for asking this question is that should MegaPOV be quite
similar to Pov3.5 I am going to adopt it right away otherwise I prefer to way
for 3.5.

Thanks in advance.

Thank you!! I would have traded gif support for any one of those fixes!

You can always go to http://www.tuxedo.org/~esr/gif2png/
The source is available and should work for Dos, Unix, Linux and Windows.

  AFAIK many megapov features will be very similar (if not identical) in
pov3.5, but not every single feature will be included, so be aware of that.

Actually the .pot format _is_ in gif format. The pictures are only twice
as width as the original picture, because the high 8 bits of the 16bit
picture are stored in the second half of the picture.
