    I installed WPMU Signup Captcha but there seems to be an issue where the image will not display.

    The signup page is at http://dailytestimony.net/wp-signup.php letme know if it works for you because maybe its just a browser thing, I am using IE7.

    From phpinfo:

    gd
    GD Support enabled
    GD Version bundled (2.0.34 compatible)
    GIF Read Support enabled
    GIF Create Support enabled
    JPG Support enabled
    PNG Support enabled
    WBMP Support enabled
    XPM Support enabled
    XBM Support enabled

    A quick look at your outputted code for that page and looking at what's there for the image URL should tell you exactly what the problem is.

    <img src="wp-captcha.php?rand=193729" alt="Captcha code" border="0" />

    So I decided to do a test, I went to wp-captcha.php and it gives an error

    Fatal error: Call to undefined function imagettfbbox() in /home/dtnet/public_html/wp-captcha.php on line 38

    Now I didn't make any modifications to any of the captcha files, only slight ones to wp-signup to include a TOS checkbox.

    Well I looked at the code of wp-captcha.php and line 28 is:

    $textbox = imagettfbbox($font_size, 0, $this->font, $this->code) or die('Error in imagettfbbox function');

    Now i'm not sure where imagettfbbox is supposed to be defined so I can look any closer. Anyone have any ideas?

    Perhaps you don't have truetype support (or whatever it's called) installed in PHP. Freetype? I dunno. Anyway, that function is a truetype-related function.

    I'll be releasing an anti-splog plugin soon that will eliminate 99% of <b>automated</b> spam blogs/users and doesn't require a captcha. Just testing it out on my own blog for a few weeks to see what they can throw at me.

    hmmm, I see.

    @MrBrian That will be nice to see, also I'd like to see one that looks at new blog posts the same way SK2 or akismet looks at comments.

    I looked at both akismet and sk2 and they really wouldn't work well for identifying spam posts, but i really like the idea. I will look at the code of some other anti-spam plugins and see if i can integrate something that checks a user's very first blog post.

    yeah that would be nice to see a plugin for it. I would think anyone would work because if it can find spam comments why wouldn't it identify spam posts but I'm probably wrong about tha...their probably are some diffrences in how they are written perhaps? idk but definatley would be nice to see.

    I need a sign up captcha to stop the spambots. I installed si-captcha, but it only appears on my comments not on my logins. Any ideas?

    I think that re-captcha for MU has a blog-sign-up feature.
    Won't help much, but at least you will be helping digitizing books and generating jobs in Bangladesh :)
