They need to be somewhere on the PATH.  But Emacs doesn't require those 
image formats to display its own interface correctly (for example the 
splash screen and the tool bar), and if you include binaries of those 
libraries with Emacs, then you also need to include the exact source 
they were built from along with them (as is done in 
libxpm-3.5.7-w32-src.zip). I'd also advise to keep up with security 
bugfixes in those libraries so we are not shipping known security holes 
to Emacs users.  The last task is what convinced me to keep the 
libraries to a minimum, as at the time I was considering this there was 
a spate of security holes found in image libraries. Also, building some 
of these libraries on Windows is not supported by the standard makefiles 
and is poorly documented.
