Users can attach files to forum posts. To enable users to do this, you have to assign the Attach files permission on the forum's Security tab to the desired user roles or to all authenticated users. See Managing forum security for more details. There are also some additional settings related to attachments:
In Settings -> Community -> Forums, you can adjust the following setting:
- Forum attachments allowed extensions - you can specify which file extensions can be attached to forum posts. Enter the extensions without dots, and separate them by semicolons. If blank, all extensions are allowed.
In the properties of the Forum group web part, you can adjust the following settings:
- Display attachment image - if enabled, the system displays attached images as images, not as links only.
- Attachment image maximal side size - if an attached image is larger than the entered value, the system resizes the image so that its larger side's size is equal to the entered value.
When editing a forum in the Forums application, you can set the following property on the General tab:
- Attachment max. file size (kB) - you can define the maximum size of an attached file in kB.
Adding attachments to a forum post
When adding a post to a forum, users can enable the Attach file(s) function (if configured accordingly Forums -> Edit () forum group -> Forums -> Edit ( ) forum -> Security).
After clicking OK, a new dialog appears where users can upload the attachments. When all desired images are uploaded, users can click Back, which takes them back to the forum.
Back in the forum thread, links to uploaded attachments are displayed with the post.
