Pictures not downloading in iMessage: how to fix it

Pictures usually stop downloading in iMessage because of a weak or limited connection, Low Data Mode, full iPhone or iCloud storage, or Messages in iCloud still syncing older attachments. Work through it in this order: switch between Wi-Fi and cellular, turn off Low Data Mode, free up storage, check the iMessage settings, restart Messages and the iPhone, update iOS, and reset network settings only as a last step.

This guide covers the Messages app on iPhone and iPad (blue iMessage bubbles and green RCS, MMS or SMS bubbles) and the Messages in iCloud setting that also affects the Mac. Each fix is matched to the symptom you see, so you can skip what does not apply.

Why pictures are not downloading in iMessage

Photos in Messages fail to download when the iPhone cannot fetch the attachment from Apple's servers, has nowhere to store it, or has been told to wait. Apple's own troubleshooting for photos and videos in Messages starts with storage and connectivity, and iMessage, RCS and MMS all need cellular data or Wi-Fi to move pictures. The symptom you see points to the likely cause:

Check the connection and turn off Low Data Mode

A stable connection is the first thing iMessage needs to download a picture, and Low Data Mode is the most common setting that quietly blocks it. Apple says Low Data Mode stops automatic downloads, pauses iCloud updates and limits network use for apps you are not actively using, which can leave attachments waiting.

1. Switch from Wi-Fi to cellular data, or the other way round, and open the conversation again.
2. For Wi-Fi: open Settings > Wi-Fi, tap the Info button next to your network and turn off Low Data Mode.
3. For LTE or 4G: open Settings > Cellular > Cellular Data Options and turn off Low Data Mode.
4. For 5G: open Settings > Cellular > Cellular Data Options > Data Mode and choose a mode other than Low Data Mode.
5. With dual SIM, open Settings > Cellular, tap the line you use and check its Low Data Mode setting.

If you restrict which apps may use cellular data, make sure Messages is allowed. A VPN or security app can also block downloads: Apple's Wi-Fi troubleshooting suggests removing such software temporarily to test the connection. iCloud syncs the Wi-Fi Low Data Mode choice across your devices, so the same network may also be limited on your iPad.

Check the Messages and iMessage settings

The Messages settings decide which service carries a picture, so a wrong setting can make photos fail for one type of conversation only. On iOS 18 and later these options live under Settings > Apps > Messages; on older versions open Settings > Messages.

• iMessage: turn it off and back on to re-register the service.
• Send & Receive: confirm your phone number and Apple Account email are selected.
• Low Quality Image Mode: Apple lists it, along with photo previews, as a setting to try when photos or videos will not send or receive.
• Send as Text Message: lets a message fall back to a text when iMessage is unavailable; messaging rates may apply.

Green bubbles are RCS, MMS or SMS conversations handled by your carrier. If pictures fail only there, check that cellular data is on and ask the carrier whether MMS or RCS is active on your plan, because Apple refers carrier messaging problems to the carrier.

Free up iPhone storage and iCloud storage

Messages cannot save a picture when the iPhone is out of space, and Apple names "enough storage" as the first check for photos that will not send or receive. Open Settings > General > iPhone Storage (iPad Storage on an iPad) to see free space and how much the Messages category uses.

If space is tight, delete large videos, apps you no longer use or old conversations with heavy attachments, then try the download again. Keep a comfortable margin of free space rather than just enough for one photo.

iCloud storage matters too when Messages in iCloud is on. Apple states that messages and their attachments are stored in iCloud and count toward your iCloud storage, so a full iCloud plan is worth checking in Settings > [your name] > iCloud before you look for deeper problems.

Messages in iCloud: when older photos will not load

Messages in iCloud explains most cases where old pictures in a conversation show up blank while new ones work. Apple says that with this feature your messages and attachments live in iCloud and only the most recently accessed messages are kept on the device, so older photos have to be downloaded again when you scroll back to them.

After a new iPhone setup or after turning the feature on, Apple notes it may take some time for all messages to appear. Keep the iPhone on Wi-Fi and connected to power, with Low Data Mode off, and give it time.

To check or toggle the setting:

1. On iOS or iPadOS 17.2 or later, open Settings > [your name] > iCloud, tap See All (or Show All), then Messages in iCloud, and check Use on this iPhone.
2. On iOS 16 to 17.1, open Settings > [your name] > iCloud > Show All > Messages and check Sync this iPhone.
3. On a Mac, open Messages > Settings > iMessage and check Enable Messages in iCloud.

Every device must be signed in to the same Apple Account, with two-factor authentication and iCloud Keychain on, or its messages will not stay in sync.

Restart Messages and the iPhone, then update iOS

A restart clears temporary glitches that leave an attachment stuck halfway. Close Messages from the App Switcher (swipe up from the bottom of the screen and pause, or double-press the Home button on older models), then swipe the Messages card away.

1. Turn the iPhone off with the slider, wait a few seconds and turn it back on.
2. Open the conversation and tap the picture again.
3. If that fails, install the latest update in Settings > General > Software Update, since Apple's Messages troubleshooting lists updating iOS as a first step.

If the problem started right after a major iOS update, check for a newer point update before trying anything drastic.

Reset Network Settings as the last software fix

Reset Network Settings rebuilds the iPhone's network configuration and often fixes downloads that fail on every network. Apple recommends it only after other fixes fail, because it removes saved Wi-Fi networks and passwords, cellular settings, and VPN and APN settings.

1. Open Settings > General > Transfer or Reset iPhone.
2. Tap Reset, then Reset Network Settings.
3. Enter your passcode and confirm.
4. Rejoin your Wi-Fi network and try the picture again.

If a school or employer manages the iPhone, ask the administrator first, because the reset removes their network profiles.

When to contact Apple or your carrier

Contact Apple when blue-bubble iMessage pictures still fail after all of the steps above, and contact your carrier when only green-bubble pictures fail. Apple's guide for messages that will not send or receive also points to the carrier for RCS, MMS and SMS questions.

Before you reach out, note your iOS version, whether the problem happens on Wi-Fi and cellular, and whether it affects new pictures, old pictures or both. That information shortens the support conversation. You can start a request at Apple Support.
