Hi,

1. I am having problems to display the picture on the first page-load. The URL 
is 
   Test/Captcha?action=captchaimage&captchakey=0

and then the thing is not a picture. Tried both with Firefox 1.5 and Konqueror 
(both on Debian GNU/Linux). A subsequent page reload displays the picture 
(unless it is again &captchakey=0).

2. To properly validate, the link to the image should be escaped in HTML 
from "&" to "&".

Thanks,
Petko
