Hi Jason,
Please follow the steps to allow users to update photos,
* Login as 'admin' to ADSelfService Plus.
* Navigate to 'Configuration' tab --> Self-Service --> Directory Self Service --> Self Update Layout
* 'Advanced' column --> Click to view the advanced options --> Enable users to perform photo update
All the photos will be get stored in Active Directory under the specific user. By default, it goes to the thumbnailPhoto attribute and it can be changed to jpegPhoto if you wish.
