These are all of the configurable values and their default values:
width = 120
height = 40
characters = 5
bgcolor = FFFFFF
textcolor = 000000
noisecolor = 000000
font = Fonts/MOM_T___.TTF
field = 1
transparent = 0
bgimage =
gridfreq = 50
gridcolor = 000000
gridorder = behind
noisefreq = 50
noiseorder = behind
charheight = 75% of height
On your page you have an image src of:
MOM_T___.TTF
most of these are the defaults, so you might as well just have:
WAVT_CaptchaSecurityImages.php?width=200
If you want to have less noise you can do something like:
WAVT_CaptchaSecurityImages.php?width=200&noisefreq=20&gridfreq=20
If you want to change the background color to red you would use:
WAVT_CaptchaSecurityImages.php?width=200&noisefreq=20&gridfreq=20&bgcolor=ff0000
and if you want to change the text color to green you could use:
WAVT_CaptchaSecurityImages.php?width=200&noisefreq=20&gridfreq=20&bgcolor=ff0000&textcolor=00ff00
