I meant that, but as said it's IMHO not worth it the processing overhead, aus you can simply turn off displaying eMails.

I'd call the image something like this,

PHP Code:

  $im     = imagecreatefrompng('email-' . $userinfo['userid']  . '.png'); 


Erm ... for this to work you would need tohse image-userid.png files on your servers HD
The users browser never gets to see this email.png, however if you want to prevent caching (which should only be an issue when a user changes his eMail) you can add No-Cache Headers.
