Respond to a friend’s photo collection sent received in iMessage.

In iMessages, I received a photo collection from my sister in law. The pictures were from my nephew’s wedding. My SIL too, has an iPhone. I have an iPhone 13, and I don’t know what she has.

she sent me 20 of the best pictures taken that day. I want to respond to each photo individually. There must be some way for me to scroll through each, and make my comment which then I can return text. And that way, when she receives my text, she’ll be able to see exactly what I’m talking about. Thanks for your help
