Glad to help:
- “Images uploaded by posters using this plugin who are not logged in display this in the Attachment details in the Media Library: ‘Uploaded by: (no author)’.”
Thanks for reporting, this looks like a bug for users who are not logged in to WordPress when submitting a post/images. So while logged-in users will have their name displayed next to images in the Media Library, the name is missing for users who are not logged in. I will get this fixed up in the next version of the plugin.
2. “I’d like to be able to display all images uploaded anonymously in the library. Is this possible using a plugin hook?”
It’s not a plugin feature, but it may be possible in general if there is a hook for media display, depending on location (i.e., front end or back end).
3. “Another thing, since the WP “ajax_query_attachments_args” filter can be used to filter images shown in the library by user ID, it would be nice if we could set an image’s user ID attribute to something for anonymous posters when they submit their post.”
Yes that is how it supposed to work by default. The user name associated with images is determined by the plugin setting, Assigned Author. As explained in #1, there is a bug where no name is displayed if the user is not logged in when submitting a post/images. If you log in and try again with some images, you will find the user name is displayed correctly. Again, I will get this fixed up next plugin update.
Thanks for your feedback, let me know if I can provide any further information. Glad to help anytime.
