Hi Julie!
Sorry for the delayed response - I’ve had a major project deadline. I noticed You put this question up as a separate post. My answer is different than Trey’s, in case You were meaning what is my understanding of your question. (His answer is a good one, just a different take.)

Note that I animate the “top” and “left” of the image so it slides as it zooms (Scene “NYC1”).
You can also elect to create a “Motion Path” instead of my “left~top” keyframes.
