So we've seen Google introduce image proxying (rehosting) to spot and destroy potentially dangerous exploits within images. Blocking images by default in email clients has always been a lazy way of protecting users, so I'm impressed Google have finally addressed this within the Gmail web interface.

However, as Email Analytics has shown, very few users actually use the web interface. It stands to reason that they'd want to protect their users however they choose to read their email. It's certainly not technically challenging.

Do you think Google will eventually proxy email images everywhere, even when accessed via desktop or mobile email clients?
