Re: CAPTCHA image validation in web form

Brad,

Yes I think also in a way of shows some info in an div/popup/ajax but the
customers are seeing all these nice captchas and "how to easily is it
possible".

also in my case I need this app multi language (at least english, spanish,
portugese, maybe catalan and french, even german), then typing english words
would not be welcomed to all users.
maybe some more simple as A6745C is neutral.

using a remote external web services for generating the image will be slow
and will be problematic in the future,
some examples of web services would be:
http://www.1888pressrelease.com/captcha-cc-launches-new-web-service-pr-tcx06l928.html
http://www.trynt.com/trynt-captcha-api/
searching in google using "captcha web service"
but would be great if locating only "proffesional" services and not all
these results.

keep on...

Guillermo.

I'll be interested in this too. I've never done it, and could most likely
figure it out, but I'm sure one of the days one of my customers is going to
want it. :)

I had issues with bots on my website forum software one time. I almost
looked into it then, but instead created a simple onSubmit javascript that
threw up a dialog saying "do you really want to post this?" and when they
clicked OK it changed another variable and went into my CGI app. That way
it couldn't by bypassed unless they figured out what the name of the
variable I changed and the value was.

Worked for a year, but one spammer actually figured it out and changed
their
bot. I was like "well, someone is sure bored!" lol..
