Educated guess: this should be
  moll_fb_LDADD = $(LIBS_IMAGE)
right?  No need to add $(LIBS), they are added by default anyway.

This line should not be necessary at all.

Typo in your mail?  That should be
  AC_SUBST([LIBS_IMAGE], [-lpng -lungif -ljpeg])

but most likely you'd want to add a couple of tests with AC_CHECK_LIB
for availability of the libraries.  If you don't know how to do this,
be sure to read the docs and look at how other packages do this.

Cheers,
Ralf
