1) It seems atoz.ttf is not really a good font for displaying captchas. Captchas can contain numbers but the font seem to support only letters.
index.php?t=getfile&id=6187&private=0

2) Without ttf support the captcha are hard to read. For example, this is supposed to be 578G. It does not seem to be possible to choose a larger font size with imagestring(), but maybe we could reduce the fading in this situation. Without it the captchas are clearly readable.
index.php?t=getfile&id=6189&private=0

3) Looking at the code imagettfbbox() is called to test for ttf support. I am not sure what happens if ttf is not supported. Maybe we should prefix it with @ to suppress warnings that might be thrown.

You are welcome to change it.

1. This is in "atoz.ttf". You can remove or replace the font file.

2. Sounds good.

3. Also OK.

PS: Please let me know how much time you need. We can implement this is 3.0.3RC1, but RC2 will only have critical fixes.

I committed the changes and my other pending bug fixes. For now I just removed the font. Maybe we can look for more suitable fonts later.

Excellent. Thank you very much!

Just one question, do we really need the extra "if (defined('__adm_rsidl')) {" in footer.php?

I saw a warning about undefined constant __adm_rsidl after calling admloginuser.php. This is supposed to be a quick fix for it, maybe there is a better one.
