echo text - anti-spam-spider measure

I need an anti-spam-spider measure for my site. Too many addresses are getting raked. In once instance, I created a flash page: http://erasethis.glquebec.org/English/contact.htm But I just don't have the time to create a flash image for every single instance, most of which come from dynamically printed PHP pages from a MySQL database. Could I dynamically create a flash image, input the email and tell the flash image to mailto:the@address.com? Do anyone have a solution? Does one already exist? My idea was to create a PHP script and output to a png. But I see many problems, including: 1) How do I avoid echoing the email address in the <a href=""> tag? 2) How would I write a png that would be long and high enough? 3) How would the same script display the png? In short, I can't see far enough how to do this and avoid spider-raking in the HTML or header the content of the image. Any advice, code or input would be appreciated, John <a href="<?php #what do I put here? $mydata->email = "me@somewhere.com"; echo $??????????; ?>"><img src="<?php |header('Content-type: image/png');| #How do I display the image? $mydata->email = "me@somewhere.com"; echo $??????????; ?>" width="???" height="???">
