More of these pictures. I'm a first time homeowner and gardener.

Hi, I'm attaching a couple of pictures. I pulled out some vines along our chain link fence two weeks ago and now I have rashes all over my arms. First time so I had no idea what a PI looked like. Now I can't remember which vine it was that felled me. Could you let me know which is PI/PO/PS versus the ok stuff? Thanks.
