The electromagnetic form factors of the Delta and Omega baryons arecalculated in the framework of Poincare-covariant bound-state equations. Thequark-quark interaction is truncated to a single dressed-gluon exchange wherefor the dressings we use two different models and compare the results. Thecalculation predicts an oblate shape for the electric charge distribution and aprolate shape for the magnetic dipole distribution. We also identify thenecessity of including pion-cloud corrections at low photon-momentum transfer.
