Well, both really. Pmwiki is better than many in readability, but too small.

1) The field and numbers are really tiny, so many people find it
difficult to see. There should be an easy way to scale the size.


2) Accessibility. There is no audio playback option so that visually
impaired users can listen to the code spoken aloud.

I found an Open Source PHP image captcha which has audio playback of
the captcha code, and it was quite easy to scale the size. Here is the
scaled demo I put up** :

The original demo is at:

** Note: My scaling seems to have caused a bug in audio playback, it's
saying more letters than are there, but this does not happen in the
original.
