Have been watching this go back and forth & get further from the original
question as usual. I suspect that if the original poster looks in her/his/
its/other SYSTEM.INI file, the line "display.drv=vga.drv" will be found in
the [boot] section. This is the default 16 color driver installed by
Windows to be compatible with every 256k 640x480 VGA card.
This makes a decent GIF or JPEG - even "64 gray scale" such as the
QuickCam produces - look like olifactory solid waste products.
To do better, you need three things:
1) A video card with higher resolution (usually at least 1 Mb of video
memory is necessary).
2) A video monitor capable of supporting the card's output.
3) An increased resolution (at least 256 colors as the first responder
mentioned) video driver to replace vga.drv (YMMV).
If any of these are missing, see the second paragraph above.
Warmly,
Padgett
