I personally do ShareX, with an SFTP destination for an nginx webserver. It has an image editor built in as part of the workflow if you enable it, and it can automatically copy the clipboard URL.
You could certainly go the extra mile and setup an image sharing manager or a more complicated solution if you wanted to though, if that makes overall administration easier.
Canada had a program like this. It was called Carrot Rewards and it paid you in points for doing health questionnaires and tracking your steps. It was funded by 3 provincial governments (for residents of those 3 provinces). Manulife has a similar program for their insured right now, awarding Aeroplan points.
