Unable to post pictures

I'm running IIS 6.0 on W2K3, and have one problem I can't find a solution to: When signing the guestbook, I've browsed to a picture, filled out the information, and submitted. The post shows, but no pictures (or placeholders) are there. The "public" and "tmp" directories are empty. I've tried this with a number of small jpg and gif files.

I've granted full access NTFS permissions to the public and tmp folders for the IUSR account, but still no luck. Can anyone help me?

Did you give write permission to the public and tmp folders? ie CHMOD them to 777

"I've granted full access NTFS permissions to the public and tmp folders for the IUSR account".

I'm not running Apache - just plain IIS 6.0 with PHP 5.0 support. From what I know, chmod 777 = Full NTFS Folder permission.

I fixed a similar problem with the animated counter by using the full local drive path on the server to indicate the "$page.txt" file location.

e.g. (!file_exists("e:\\hosting\\user\\counter\\pages\\$page.txt")

I can't say for sure, but it seems like the guestbook problem is along the same vein (it can't find the path specified, so the files don't upload).

Any thoughts?

answer lies within the php.ini configuration and location of the web folder - working properly now
