The DNN Core User Accounts Module is built to be used by Admins. It checks for Admin rights for authorizing permissions.

I had a situation, where I needed to allow Members in a particular role to have access to User Accounts (without assigning them Admin role). There were more customizations needed (like I needed the username to be automatically generated from the User's First & Last Name, e.g. rs1).

So, I have built a custom module on the lines of DNN User Accounts module. Along with other things, it allows users to upload images. There is a sample image below. See if this suits you:

As I said, I needed customizations. One of those was to have a User Profile during Registration. And that profile includes the image too.

So, in my Module, the user can actually upload the image as part of the registration process. Whether that image is compulsarily required for Registration, or whether the user is allowed to update the image are all Module Settings, that can be set by an Authorized person, having Edit or Host permission for the Module.

If you are interested, I might arrange an online demo of my module on one of my DNN installations!!!
