Generalized parton distributions (GPDs) describe the internal structure of hadrons in terms of quark and gluon degrees of freedom, combining the information mediated by form factors, parton densities and distribution amplitudes. In this talk I present results from full lattice QCD for the lower moments of GPDs, from which images of the spatial distribution of charge and spin in the fast moving nucleon are derived.
