[l2h] changing to 24 bit color depth of images/ keeping existing jpg images?

I got rid of some of the problems with the image
processing my self:

Image conversion/scaling of images works fine on win
XP as long as:

1) The .tex  and the image files are on the same

2) one specifies relative paths i.e. without using the
drive letter in the  Latex include graphics command.

3) have a file extension in the include graphics

There is a very peculiar thing when the full path
including drive letter is used in the \includegraphics
command, e.g.


then the resulting image is not scaled but resized by
L2H to the size specified in the "image.bb" and
resized image is in grayscale, whereas as the original
was in color. 

In the case the tex source and the image files are on
separate partitions, maybe the variable $GRAPHICS_PATH
that could be set to take care of the problem?

see the previous mention thread on

appreciate any comments/suggestions
