This is @Chundi_Jr and me at fall of last year. Just thought I'd share a family photo with the people of ECC!
I would have voted for "me" because "This is [...] me". Not sure whether it differs in some countries though, language can be annoying.
I is the first person singular subject pronoun , which means that it refers to the person performing the action of a verb. I want to go. This is the one I like. You and I need to get ready. Tom and I are going to the movies. Me Me is an object pronoun, which means that it refers to the person that the action of a verb is being done to, or to whom a preposition refers. David told me to leave. He gave me ten dollars. Between you and me, this is a bad idea. She needs to talk to Joe or me.
