In a photo caption, if we use the elliptical 'My kids and me', would 'me' be correct, or would 'I' be correct? It seems as though it could go both ways. 

[This is a picture of] 'My kids and me' or 'Me and the kids'.

Or,

'My kids and I' [are in this picture]

Which is the correct choice -- 'me' or 'I' in these elliptical constructions?

Thank you
