I am trying to use a CGI .exe program that needs to write a graphics file to
a local directory, such as images. Trying to open the file for writing
fails. I wrote a simple test program that verifies the behavior. I suspect
that it is a permissions issue, since I can open a file for reading from the
same directory in my test program. I have set the permissions on the images
directory to read and write. I have even added the Users group to the
IUSR_<machine> account. What do I need to change to be able to write a file
from the CGI program?
