Using GD Library to Hide Email Addresses from Bots
Posted: Sun Jan 18, 2009 1:42 pm
Hello,
I am an amature PHP coder, and recently I've heard about using the GD library to change e-mail addresses to images. The theory behind it is that it prevents spam bots from harvesting e-mail addresses because it cannot see any of the characters.
I have been unable to find any tutorials on how I would be able to design a script to do this. I just need an image to be produced somewhere on my server. Perhaps the script would accompany a web page I could go to to input a text string, click submit, and have it converted to an image. Thanks!
