The agreement found with the $γ_v p\toΔ^0π^+$ and $γ_v p\toΔ^{++}π^-$ reactions is good. The sensitivity of the results to $NΔ$ transition form factors is also studied. The present reaction, selecting a particular final state, is an extra test for models of the $γ_{v} N\to ππN$ amplitude.4 pages, 2 figures, Talk given at Meson 2000 Workshop, Krakow, Poland, 19-23 May 2000Nuclear Theorytext
