The Captcha images are being created so i suspect its the path to the images
from the view scripts that is the problem. Is your path to your image in the
view code accessible by a browser?
I always use an absolute path from my web root (public or public html
directory).
For instance if you have a folder in the root of your site for images, then
"/images/captcha/"
would be your folder, etc.
Try specifying an absolute path from the web directory root.
