CAPTCHA Server

HELP

c: (color)
r, random - randomizes foreground colors instead of black/white only
(example: /?c=r)

charset:
whatever you put here would be sent as the character set to choose from
(example: /?charset=0123456789)

d: (difficulty)
0-3, 0 shows nothing, 2 adds fuzz, 3 follows a line
(example: /?d=3)

debug:
0/1, on or off, shows debug stats
(example: /?debug=1)

f: (font)
1-5,l,s - 1-5 are system fonts, only 4-5 work well, s=script, l=latin
(example: /?f=s)

i: (iterations)
1-1000, how many iterations to run, or how many captchas to draw
(example: /?i=50)

v: (view mode)
div, puts captchas in a container div rather than a single column
(example: /?v=div)

using it all together:
(example: /?c=r&charset=0123456789&d=3&debug=1&f=s&i=3&v=div)

any questions?
