I seem to have a problem creating captcha images on a Windows Godaddy shared hosting.
If I create one under the main domain name it works fine, but if I try the same code on one of the domains that are not the primary domain but under the same hosting account then I just get a blank image.
Has anybody managed to resolve this problem?
I guess I might have to specify the DESTINATION, but I'm not 100% sure what to put in there, plus I am concerned that duplicate images might cause problems. I did play around and got an error saying the image already existed.
