It's actually a limitation of the Windows parser, and memory
available. I found this out when trying to help a user with a similar
problem for a "bikini" site he wanted to pluck daily. What happens is that
when you uncompress a color image into memory, the image can become much
larger in memory than on "disk".
Since the Palm is limited in record size, Dirk has added some magic to the
parser to make sure that you can still see the image, instead of getting an
"out of memory" error from the Palm application itself.
I'll bet if you pare down the size of those alt-maxwidth images,
you'll see them in color again if you tap them, though not quite as large.
There must be a way around this, because there are image viewers
that can read very large images into memory and pan them around, but I'm not
sure Plucker can quite do that level of graphic manipulation yet. If you
were to parse the same page with the same parameters on a non-Windows
platform, tapping on the image would bring up a dialog which stated
something like "There is not enough free memory to view this image". Seeing
the image in greyscale instead of the error message is a bit more elegant,
though not exactly what you expect.
