So if you change, say, your iPhone-using ex's chat background to a Demagorgon, they're going to see that immediately.

Or, tap Photo, and select a picture from your camera roll. Your phone will suggest some options (on mine, it pulled up scenic shots I've taken on trips), or you can access all of your photos and collections. Crop the photo by pinching in or out, and swipe left to add a filter.When you find the option you want, tap the blue check mark button in the top right corner of your phone. This immediately changes the background and adds a note in the chat on your end that says "You changed the background" with the date and time stamp. That note also appears for the other people on the thread, saying "(Your name) changed the background." It's an easy way to customize your message threads and make them more aesthetically pleasing (and clear who you're messaging) -- so long as you don't mind the people on the other end seeing them, too.

This allows them to see it on their end, but you don't have to see it on yours. Do this by going to Settings > Apps > Messages, and toggle Conversation Backgrounds off. If you changed a message background and want to go back to a plain one, go to the Messages app, and open the conversation. Tap the contact name or group icon at the top, and tap Backgrounds. Then tap None. Just note that this option will remove the background image for the other members of the chat, too.
