No. As others have said, NXLIB is only used when connecting
gui libraries written for X11 with nano-X. These libs include
FLTK, GTK, etc.

NXLIB replaces libX11.so. If this lib isn't used, no need for it.

This is the correct behaviour, and your white transparency bug
is fixed, for bmp image types. BMP images don't support
transparency. This bug was fixed in CVS some time ago,
and is not fixed in 0.91.

This then is likely a jpeg only bug/issue. Look at the source
code engine/image_jpeg.c. To help you more, we need to
know what framebuffer format you're running, bpp, and
palette mode or not. Check whether FASTJPEG is set
in image_jpeg.c.
