Hello! I understand you're having trouble with images not loading on the Jumia Online Shopping app on your Android device running version 7.0 with WebKit browser. Let's work together to get this fixed.

First, could you tell me whether the problem happens only on the app or also when you try browsing Jumia through WebKit? Also, have you noticed this issue with all images or only in certain sections or products?

Meanwhile, here is a step-by-step solution you can try:

1. Check Internet Connection: Ensure your device is connected to a stable and fast internet network. Sometimes images fail to load on slow or unstable connections.

2. Clear App Cache and Data:
- Go to your device's Settings > Apps > Jumia Online Shopping.
- Tap Storage.
- Clear Cache first and see if images load.
- If not, clear Data (note this will log you out, so have your login info handy).

3. Update the App: Make sure your Jumia app is updated to the latest version from Google Play. Older versions might have bugs causing image failures.

4. Reinstall the App: If updating does not help, uninstall and then reinstall the app to get a fresh installation.

5. Check App Permissions: Ensure the app has permission to use storage and data on your device:
- Go to Settings > Apps > Jumia > Permissions.
- Enable any permissions related to storage and network access.

6. Switch Network: Try switching between mobile data and Wi-Fi to rule out network issues.

7. Disable Data Saver or VPN: If you use data saver mode or VPN, disable them temporarily as they may interfere with image loading.

If you've tried these steps or the issue persists, there might be an underlying glitch or server-related issue. Let me know what you've tried and we can dive deeper.

Would you like me to guide you step-by-step through these fixes?
