    View attachment 2432

    Sorry there is no live demo at the moment, i have problems with my free host.

    this captcha make it harder for bots crack the code.

    just replace the capcha folder with the one from this page

    + it has multi language audio just add your language to the audio folder as you would do in the languages EN DK etc. and it takes the correct language if its there else it uses the default English one.
    Dk is there as example you can delete that folder if you not use Danish.

    Note i have made some small changes to the layout of captcha to fit my theme so i am not sure how it fits the default theme i hope it is all right.

    I never even thought about the captcha for different languages as far as the audio goes. I will have to find some audio in Español. Good thinking Dahlsvarehus.com on making it Universally friendly for different languages.

    I haven't tested this out yet but, I will soon. I actually like the first fonts you used that were harder to read because of the thin lines that something got hidden behind the grid lines. I thought it made it hard for the bots to read them because the grid lines hid the lines on the characters.

    RE: Version 001

    I have changed the mod category as this is more of a "Feature Enhancement" than it is a "New Feature"

    I have no clue where the "RE: Version 001" is coming from above but the forum won't get rid of it, I even completely deleted the post physically Removed it from the database and re posted it but its still there

    I actually just tried this. The 1st captcha dahl made had characters in different colors. I noticed today that all of the 8 characters were only being read out in audio with only 7 characters. I thought I tested that before. This doesn't work on my webid site with the audio. I have a blind friend who uses the PC and pretty good at using the pc without his vision. He would need to hear the letters correctly.

    I haven't tested out this new improved captcha version. I am tempted to take my security codes down and let the bots have a go at this one. This one doesn't look as hard to penetrate. For fun, I think I will test it now and report back.

    I would of reported back sooner but, after the spam bots saw the dahl's new and improved captcha, they ran away and I couldn't run any tests without them. I had opened my webid site up and removed and restored my .htaccess file to the original code to allow bots to get on my site so, I could test out this captcha. As soon as I put up a real register.php in the proper place, I only had 6 attempts and then today, I had hardly any activity on my site at all. I finally got some bot activity this evening. It's like they were shut down or something for the day or something. Maybe a power outage. I keep getting the same IPs from Paris, France that have been hitting my page for over a month. I wish I could zap their computer and remove their spam bot program.

    Here's a photo of their activity. Maybe some of you have these same IPs hitting your page. The 195 and 198 are the Paris, France one that I see hitting my site all month. There was 59 attemps the bots took at that captcha in a 4 hour period and no bots got by it. I will just share a few in the photo.

    For the record, I have no links leading up to my register.php page. The bots go directly to the register.php page.

    I've seen enough now. This captcha passes but, needs some coding on the audio part. The bots are really coming at my site now. They are not registering but, they are making a mess in my visitor log. Back up go my .htaccess codes. Time to rename my register.php page again too.

    I am curious though if what if I let those two on from Paris France. If I let them on and then deleted their accounts, would they stop trying to sign up? What would probably happen is they will probably disappear on me and then maybe new proxys would hit me and I would have to make adjustments. I better just not let them in. :p

    RE: Version 001

    It should say in the instructions but incase it does not.

    Open the file includes/captcha/securimage.php and on line 465 find the code
    PHP:
    <input type="text" name="captcha_code" size="5" maxlength="4" />
    Replace it with code
    PHP:
        <input type="text" name="captcha_code" size="8" maxlength="8" />
    Save the file and reupload
