Ghostscript already preserves images at their native resolution in general,
and even when it does not (for example flattening transparency) it uses the
specified resolution, in your case 300 dpi.

How are you determining the image resolution of the original images, and
the images in the created PDF file ?

You don't say which version of Ghostscript you are using, nor which
platform you are running on, and obviously you haven't supplied a test file
for us to look at, its going to be pretty nearly impossible to help you
without all that information. BTW you also don't seem to have discovered
the image downsample controls 'xxxImageDownsampleThreshold' and
'xxxImageDownsampleType'

If you are using the latest version of Ghostscript, and are sure this is
still a problem, then your best bet is to open a bug report at:

http://bugs.ghostscript.com

Once the report is open you can attach files to it, if they are sensitive
then you can mark them as private, which limits their availability to
Artifex employees.
