Save MD5 for all directions of the arrow and >compare :) Tijnema: Okay, here's an example: http://sperling.com/a/arrows/ How would someone MD5 that? Furthermore, how would a bot decipher anything different from that? From my perspective, no matter which way the arrow is pointing, the code remains the same. The only thing that changes is the arrow and a screen reader would have to be programmed to recognize the change -- am I wrong? Cheers, tedd
Well, I cracked it for you :) http://86.86.80.41/dev/debug/tedd.php At the bottom it shows you the MD5 code of your arrow image, and it shows you which way it points to :) If you're interested in the code: http://86.86.80.41/dev/debug/tedd.txt Tijnema -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
