Accounts without administrator or webmaster privileges are limited to editing library items that they own. This behavior can be changed with a plugin.
Why can’t publishers edit certain images, documents or people in the Big Medium library?
Accounts with administrator or webmaster privileges can browse and edit all library items. Other types of accounts (publishers, editors and writers) can edit documents only if they own them. Administrators and webmasters can, however, change ownership of any library item if you need to transfer ownership to a different account.
Big Medium allows you to limit individual editors, writers and publishers to specific sections of the site so that certain content is off limits for editing. Library items, however, are sitewide. So, if publishers could edit others’ library items, a publisher with limited site privileges could edit a document that is attached, among other places, to a page that they would not otherwise have permission to edit. That undermines the ability to limit publishers to certain sections. After going to and fro on this during the design, I decided to go with more security and limit publishers (along with writers and editors) to editing only library items that they actually own.
Yes, with the help of a plugin. This plugin allows publishers to edit any library items (images, documents, audio/video files and people), including items that are owned by others or items that are used in sections where the publisher does not have privileges.
Unzip the plugin download file to get a file named library-permission.pl.
Set your FTP client to “plain text” or “ascii” mode.
Upload library-permission.pl to the moxiebin/plugins directory on your server:
moxiebin/plugins/library-permission.pl
You’re done! Any user with publisher permissions at a site can now edit any library document.
