[SOLVED] Profile image permissions was created by NickC4555
I have recently built a site on Windows Server 2008 R2/IIS 7.5 and have a problem with profile image permissions. Images uploaded by users only have the following permissions:
System: Full control
The user account that uploaded it: Full control
Domain admins: Full control
IIS_IUSRS: Read
All of the corresponding thumbnail images in the same folder can be accessed by everyone. The permissions on the folder (images/comprofiler) allow all domain users access too, it's just the profile image files themselves that are locked down.
I'd be grateful for any suggestions.

Sorry, no experience with IIS. What's wrong with the permissions specifically? Are images not displaying on profile after upload? Have you checked to ensure you don't have image approval enabled within CB > Configuration > Images.

Windows files don't have generic permissions as they do in Linux, permissions are granted to individuals and groups. For users to see a file, they have to be a member of a group that has permissions on the object. On my Windows system, CB users can see their own profile images because they are a named user on the file, but no other user can.
Somehow when CB uploads the file, it is overriding the permissions that should be inherited from the folder setting, but not on thumbnails, only the main image.

Right, I understand Windows permission, but is first report of this; thank you for the further details.
CB does a chmod on the images to 0644 after completed upload, which gives write access to owner and read access to everyone else. Read access is sufficient for the image to display and other users don't need write access.
Does manually adjusting file ownership resolve the issue? Perhaps review your server configuration to ensure it's handling file permissions properly.
Sorry, while my platform is Windows I've zero experience with IIS so not much more I can advise.
You can find CBs image handling in its image library below.
administrator/components/com_comprofiler/imgToolbox.class.php

I have no idea what chmod does on a Windows system! Before your reply I had already tried commenting out the chmod lines and it makes no difference.
Manually adjusting file ownership does resolve the issue. The server permissions are set correctly; a file copied in to the images/comprofiler directory inherits the folder settings as it should.
I think the most significant factor is that the main image gets the wrong permissions, but thumbnails, which CB stores in the same folder, do not, so something is being handled differently for these two files that are created at the same time.

Is there any chance of asking the developers what the difference is between the main image and thumbnail creation, please? If they both worked the same way as the thumbnails, it would solve the problem.
