I will present the results of recent lattice simulations of the
electromagnetic form factors of the octet baryons from the CSSM/QCDSF/UKQCD
collaborations. The focus will be on the analysis of those results using techniques
to approach the infinite volume limit and the physical pseudoscalar masses at
non-zero momentum transfer. The extrapolated proton and neutron form factors are
found to be in excellent agreement with those extracted from experiment. Given the
success of these calculations, I will describe how the strange electromagnetic form
factors may be estimated from these results under the same assumption of charge
symmetry used in experimental determinations of those quantities. Motivated by the
necessity of that assumption, I will explore a method for determining the size of
charge symmetry breaking effects using the same lattice results discussed
previously.
