  We study the octet baryon electromagnetic properties by applying the
covariant spectator quark model, and provide covariant parametrization that can
be used to study baryon electromagnetic reactions. While we use the lattice QCD
data in the large pion mass regime (small pion cloud effects) to determine the
parameters of the model in the valence quark sector, we use the nucleon
physical and octet baryon magnetic moment data to parameterize the pion cloud
contributions. The valence quark contributions for the octet baryon
electromagnetic form factors are estimated by extrapolating the lattice
parametrization in the large pion mass regime to the physical regime. As for
the pion cloud contributions, we parameterize them in a covariant,
phenomenological manner, combined with SU(3) symmetry. We also discuss the
impact of the pion cloud effects on the octet baryon electromagnetic form
factors and their radii.
