Me and Jon Garland! Actually, the phrase "Jon Garland and I" would only be necessary if I were to describing an action afterwards. Such as, "Jon Garland and I were talking..." I wrote it so that if I were to add "This is a picture of..." the sentence would read "This is a picture of me and Jon Garland." Not the other way around. But I suppose it works both ways.
You've just brought out my inner grammar nerd, lol.
