We calculate the contributions to nondiffractive psi photoproduction due to the mechanisms of gluon-gluon (gg), light-quark--antiquark (qq-bar), and charmed-quark--antiquark (cc-bar) fusion. The qq-bar and cc-bar fusion lead to measurable cross sections at moderate x/sub psi/. This presents an opportunity to measure quark distributions in the photon as well as the charm sea of the proton.
