There isn't a way to see the pics you send/sent between you and the person you're texting without having to scroll through your messages to find them. When you click on a person's bubble and the options pop up, there should be a "shared media" option you can click on to see all the pics, gifs, and videos you've shared with that individual. You should be able to scroll through all the "shared media" and when you click on the individual pic, you should have the option to jump to that particular part of the conversation or save the pic!! Would be a great option!!
