This is just the standard way, but you have to write the labltk path:
     ocamlmktop -o ocamlbigtk bigarray.cma -I /ocaml/lib/labltk labltk.cma

They are different types of images. You should get info under the
image, bitmap and photo names.

Not my speciality, but if I remember correctly, not only integer
arrays are unboxed (no reason to box integers anywhere), but to get
the best efficiency you must use Array.unsafe_get, and tell the
compiler that your array contains integers (arr : int array), if it
cannot infer it.
