That won't work, as it would fail the original requirement

My forum members were complaining about the load of spam they received after the emailaddresses were publicly viewable.
We wouldn't use the secure mail function, because the users wanted to see eachothers mail addresses.

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.

What would be best, IMHO, and eliminate some of the overhead, is to be able to generate the image without calling a new php file.

Is this doable? Can it be done in a plugin through a hook? And be able to show the image on the fly?
