[nycphp-talk] Making text hard to copy

Anthony, I think for the average visitor to a web page, I would look  
into outputting the text as an image. This way it could be made to  
look like a regular web page and doesn't require the visitor to  
install or update anything on their computer such as Flash. I remember  
seeing some routines built-in to PHP that including writing text over  
a graphic. The graphic could be simply white to look like the  
background of the web page or whatever the design is.

You could write some test examples and run them at the Linux command  
level using the 'time' command to see how much overhead they really  
add vs displaying the text:

time php textasgraphic.php
time php justtext.php

Before anyone else further beats up on the concept, I can understand  
why someone would prefer not to have people copy and paste their  
content out of context and  e-mail it around such as a company news  
release, where the company would prefer people direct others to the  
web page itself.
