    captcha

    i'm getting a lot of people spamming a php script i wrote, it's obviously someone wrote a bot to spam the users of my script. the best solution would be to put a captcha on the join page... but what's the best way to do that? are there libraries available? do they dynamically generate images, or are they premade? if they aren't premade, how do u deal with people whose hosts don't have gd?
