Control the origin of where images and files are sourced from, including a phone's gallery, camera, or file system. This capability confirms that images can't be reused and verifies that they aren't AI-generated.
## Before you begin
Role required: admin
## About this task
You can limit the origins of attachments to ensure that images are sourced from one or all of the following:
* On-site via a camera
* From the user's phone gallery
* From the user's file system
{#attachment-source-define__ul_njp_plv_12c}This feature is supported for all attachment locations including: activity stream, functions, and input form screen. Within the input form screen, attachments can be added from the following areas, as shown in the table.
Note:
You can source image attachments from the camera and the gallery from both these areas. You cannot source videos or record videos. Only from the input action menu can you source images from the file system.
