change your images to png (without optimized palette in order to keep
your current palette) and then do a search/replace to find all gif
references in your pov files and change them.

Believe it or not, this is the first I've heard of it. If that's the
way they're gonna be then good riddance, who needs GIFs!

I love that lossy grainy compression and unnecessarily big file sizes! I love
GIF!

Seriously how did you miss it? - have U never tried to use gifs in MP0.5a
before now?
> If that's the way they're gonna be then good riddance, who needs GIFs!
Absolutely no-one png is better anyway
Hey U have gifs on your pages
http://www.getinfo.net/douge/portfolio.htm
http://www.getinfo.net/douge/miscart.htm
http://www.getinfo.net/douge/linkpage.htm
Care to convert them to pngs using gif2png?
win console version at http://pegasus.uni-paderborn.de/enno/burnallgifs/
more (newer) versions at http://www.tuxedo.org/~esr/gif2png/
or http://exe2bin.com/gif2png-win32/

Okay, here's where it gets weird then. I just ran the code in my regular
version of MegaPOV 0.5 with a GIF image for my heightfield and
it worked. Import the same code into Mikes patch and I get the
error. Am I missing something?

At a guess and iirc, you're using mp 0.5 (which afaik supports gifs). It is
mp 0.5a that doesn't support gifs. Mike's patch is presumably based on mp
0.5a.

GIF, used correctly, is not a lossy format, nor does it have
unnecessarily big file sizes. If the image has less than 256 colors, GIF
preserves the colors completely; as the number of colors drops, the
likelihood that GIF will be much smaller than JPEG increases.
See http://cerebus.acusd.edu/GIFJPG/ for an example of an image that is
either 10 times as big as a JPEG than as a GIF, or is only 3 times as
big but much lower quality.
PNG is even better, but PNG support in web browsers is still lacking,
especially when it comes to transparency and simple animations.
(Also please note that I support the authors of software such as MegaPOV
and GD removing GIF support from their creations.)

Jpeg's not that great either. And most of the compressors for jpeg aren't
very good.

Exactly, PNG is the greatest!
