+## (Advanced, Optional) Allowing Notification Images
+
+> If you want to know more about the specifics of this setup read the [official Firebase docs](https://firebase.google.com/docs/cloud-messaging/ios/send-image).
+
+On Apple devices, in order for incoming FCM [Notifications](notifications.mdx) to display images from the FCM payload, you must add an additional notification
+service extension. This is not a required step.
+
+### Step 1 - Add a notification service extension
+
+- From Xcode top menu go to: **File > New > Target...**
+- A modal will present a list of possible targets, scroll down or use the filter to select "Notification Service Extension". Press Next.
+- Add a product name (use `ImageNotification` to follow along) and click **Finish**.
+- Enable the scheme by clicking **Activate**.
+
+![Xcode - Add a notification service extension](ios-notification-images-step-1.gif)
+
+### Step 2 - Add target to the Podfile
+
+Ensure that your new extension has access to Firebase/Messaging pod by adding it in the Podfile:
+
+- From the Navigator open the Podfile: Pods > Podfile
+- Scroll down to the bottom of the file and add:
+```ruby
+target 'ImageNotification' do
+  pod 'Firebase/Messaging'
+end
+```
+
+- Install or update your pods using `pod install` from the `ios` and/or `macos` directory.
+
+![Xcode - Add target to the Podfile](ios-notification-images-step-2.gif)
+
+### Step 3 - Use the extension helper
+
+At this point everything should still be running normally. This is the final step which is invoking the extension helper.
+
+- From the navigator select your `ImageNotification` extension
+- Open the `NotificationService.m` file
+- At the top of the file import `FirebaseMessaging.h` right after the `NotificationService.h` as shown below:
+```diff
+#import "NotificationService.h"
++ #import "FirebaseMessaging.h"
+```
+- Replace everything from line 25 to 28 with the extension helper:
+```diff
+- // Modify the notification content here...
+- self.bestAttemptContent.title = [NSString stringWithFormat:@"%@ [modified]", self.bestAttemptContent.title];
+
+- self.contentHandler(self.bestAttemptContent);
++ [[FIRMessaging extensionHelper] populateNotificationContent:self.bestAttemptContent withContentHandler:contentHandler];
+```
+
+![Xcode - Use the extension helper](ios-notification-images-step-3.gif)
+
+### Step 4
+
+Your device can now display images in a notification by specifying the `imageUrl` option in your FCM payload. Keep in mind that a 300KB max image size is enforced by the device.
