 Change Your Friends’ Profile Picture ON WHATS APP

Nah, you’ll not be making the change globally, but changing your friend’s profile picture only on your phone is sufficient to scare the hell outta him. Here’s how you can do it.

1. Choose a profile picture for your friend. Use Google Image search for cute looking monkeys and donkeys or weird looking people.
2. Resize the image to 561×561 pixels using Paint or Photoshop and name it with your friend’s mobile phone number.
3. Save the image in SD card -> WhatsApp -> Profile Pictures. Overwrite an existing image if required.
4. Disable WiFi and data network. If you don’t WhatsApp will automatically update the picture. Now show it to your friend who’ll panic instantly!
