Captcha Image not working

Hi,

I tried a few months ago to list my site on DMOZ but the captcha image wouldn't display at all. Apparently from reading some things I found on the net, there is supposed to be a link to an audio version but I can't see this either. I tried again today but it still doesn't show up.

Interestingly, the captcha for when you sign up to the forum works perfectly.

Captcha on DMOZ is working normaly.
Some people seem to have problems. Caused by the settings of their browser.
You could try clearing you browser cache.

DMOZ does not have an audio version of their captcha.

This forum has no (official) relation with DMOZ and it has its own software with own captcha.
