SharePoint Folder Permissions and Thumbnails

    Question

  • We have a large SharePoint list which contains digital assets. Some of these assets are sensitive and we have managed to achieve isolation by creating folders and breaking inheritance and adding individual users to these folders.

    The assets also have 2 types of thumbnails; a small one to show in the list view and a larger one to show on mouseover. These thumbnails are transcoded by a custom solution and saved in the _t and _w hidden folders (the same one SharePoint also uses btw).

    We are finding that after granting permissions on indivisual folders directly, some users are not able to see those thumbnails. I have verified that the thumbnails are present and can see them as a site collection admin.

    The users are being granted "Limited Access" on those special folders.

    So:

    1. How do we grant permissions so that the users can also see thumbnails?

    2. Are we doing the correct thing by granting the "Limited Access" permission or is another permission level required to see thubnails?

    3. I really hope we do not have to mess around with the _t and _w hidden folders.

    Any help is appreciated.

  • The issue was solved by giving Read Permissions as well as View Application Pages permission. After this, the user could see the contents of the folder as well thumbnails.

    Thanks to my colleage Doug Myers who was able drill down to the issue after some painstaking research!

  • Limited access is normally applied automatically at a higher level so that users with that access can traverse a higher level.

    Perhaps you could use Librarys instead of Folders and make it a bit cleaner?

  • @Chris,

    Not quite what I am looking for.

    I specifically need some clarification on the relation of thumbnails and hidden folder permissions w.r.t. its immediate parent folder.

    Thanks.

  • Hi,

    Have you tried using Read permissions? or else you can create a new permission level.

    Thanks!!
