Cant upload images

I can't upload images in the catalog area at all. My setup and installation went fine, but while trying to upload images anywhere i get these errors. I have looked for a day and a half to find an answer. I have check my permissions and they are all set to have full access, i am using iis, has anyone seen this before and can give me help. thanks

You have a permissions problem writing to that folder.

With Windows hosting it's often necessary to talk to the hosting company in order to set certain folders as public-writable (ie: by the Internet Guest Account).

Thanks for your reply. My company hosts the site so I have access to the server and the image folders are set to IUSR_WEB with all permissions: modify, read, write etc. I even made a new folder under Images and gave it all permissions with no luck. :(

I guess the next step is to research the possible causes of PHP not being able to complete its move_uploaded_file() function

move_uploaded_file(): Unable to move 'C:\PHP\uploadtemp\php90.tmp' to 'D:/nationaldiscountnutrition.com/images/manufacturers/picture.JPG'Either it cannot read it from the place it uploaded it to, or cannot write it to its destination.

Perhaps studying at php.net or webhostingtalk.com might be starting points.

Will DO
thanks a lot.

Did you manage to solve this problem? If so, what needed to be changed?

We had setup where you needed to login with user name and password to the directory. I did not think it would effect the files
but it did. We took off the login and it worked fine. It was a second
layer of security that was not needed anyway.
thanks
