I'd suggest just defining a simple directory under $datadir. No need to
touch configure.ac at all, and this method is easy to use and relatively
easy to remember. In the directory in your source tree with the image
file, put this in Makefile.am:
imagedir = $(datadir)/myappname/pixmaps
image_DATA = image.png
EXTRA_DIST = $(image_DATA)
Of course, change 'myappname' to the package name of your app. You can
add other image files to the image_DATA line, and automake will expand
that out into a set of rules to install the image files to
$datadir/myappname/pixmaps ($datadir is usually $prefix/share, often
/usr/share). If there's already an EXTRA_DIST line, add it to the
existing one instead of creating a new one.
Then, in the source directory where you want to load image.png from your
program, in Makefile.am, do something like:
myappname_CFLAGS = -DDATADIR=\"$(datadir)\"
(No, the two 'D's is not a typo.) Again, change 'myappname' to the name
of your app's binary as defined in bin_PROGRAMS in that same
Makefile.am. Note that myappname_CFLAGS will probably already exist and
have something in it; just append it to the line.
Then, in your app, you can load the image like so:
gtk_pixbuf_new_from_file(DATADIR "/myappname/pixmaps/image.png", NULL);
Again, modify 'myappname' as desired.
There are a couple more options:
$datadir/pixmaps/ is generally regarded as a legacy location for app
pixmaps. You can use it if you want, but it's far better to use the
next option.
If you want to make it possible to theme the icon, you'd want to put
your default icon in the appropriate place under
/usr/share/icons/hicolor/, and then use something like GtkIconTheme to
load it. That's left as an exercise for the reader, though ^_^.
