  Electromagnetic form factors of the baryon octet are studied using a
Nambu--Jona-Lasinio model which utilizes the proper-time regularization scheme
to simulate aspects of colour confinement. In addition, the model also
incorporates corrections to the dressed quarks from vector meson correlations
in the t-channel and the pion cloud. Comparison with recent chiral
extrapolations of lattice QCD results shows a remarkable level of consistency.
For the charge radii we find the surprising result $r_{E}^p < r_{E}^{\Sigma^+}$
and $|r_{E}^n| < |r_{E}^{\Xi^0}|$, whereas the magnetic radii have a pattern
largely consistent with a naive expectation based on the dressed quark masses.
