To the author(s) of 4image:
Hi!
I like 4image, keep your excellence work!
I'm the authur of Anti-Leech-File-Gate. I have a suggestion on anti leeching, it is maybe you can combine Anti-Leech-File-Gate with 4image to get more advanced security.
Have a look at my project Anti-Leech-File-Gate:
http://www.21code.com/alfgate/index.phpMy project is under GNU LGPL licence, so you can use it for free.
Also, I've tryed to hack 4image but I failed somehow, it's too complicated. Untill now, I've just done 1 categorie's anti-leeching and that's the maximum number I can do. I beleive there is another guy who can do this job without difficult, and that the person must be you.
