Reply To: Allowing inline images uploads in posts?
FYI: To make sure lower user roles can upload images to topics inline in their replies, the solution for me was to allow edit_others_topics and upload_files for the user role. As far as I can tell, checking this allows them to upload inline images in their comments but doesn’t let them actually edit the topics of others, oddly enough. So the solution seems to work without any additional problems being created by the extra permission.
Note: I’m also using the adminimize plugin to hide dashboard options for lower user roles, which keeps them from seeing the topics menu or anything else in the backend, so there’s no worry about them having increased permissions so long as they’re stuck only editing/commenting from the front end.
