I or Me

Either will do.

AnonymousHow do I label a picture? "the boys and I" or "the boys and me"

Either is fine. No one should notice.

This is a picture of XYZ and me taken on the cruise last year. I -will be wrong.

Or "In this picture, XYZ and I are on our cruise last year". Just like many photo captions in the newspaper, for instance, it is a fragment that cannot be assigned a sentence function.

Yes but if it was a photo of you alone, you wouldn't say "I". you would say "Me". You'd say "a photo of me", "me at the Maldives", etc.

I've just thought of a way of remembering discreet/discrete, by the way. Crete is an island that's separate from Greece.
