"Lord! What's this photograph"
(t ki m m?) <-- "t ki" is short for "qui es-tu" or "tu es qui" and even "t'es qui" in spoken french. So... "Who are you"...
I suspect "mm" is for an interrogative "huh" which in french should be written "mmh"... Further you could find "mm" meaning "même" which is translated as "even" (as in "this is even more complex") or "like" (as in "this is like this or that") according to context.

pour prendre des photos
The term imprimante in English means computer or printer. So what an imprimante photo would simply be is a computer photo, or a printer photo in English.
"Photo" in English means foto in Italian.
Translation: I feel sorry for this person, doesn't even know how to edit pictures.
