Thanks mawenzi
I already saw the caprcha FAQ. But my problem is different.I visualize the full path of the font and it's ok, but sometimes I can see captcha image and some others I can't. I jjust see the red X (missing image). Sometimes I can see the image with one click, but sometimes I have to click several times to refresh captcha image until I see one. I'm just trying in registration form. It seems a timeout problem, but my server is not a busy one, is only a development server, and it's just me working on it, so the server is completelly "relaxed". Have some ideas?
Cheers Davy
