You have an ASP.Net application. This means that the application runs on a
web server, and sends and receives HTTP messages from the client.
Specifically, it sends files to the client, and can receive Requests from
the client, which may include files, assuming that the HTML documents sent
to the client include File upload form fields.
Now, for a client to scan an image, the client machine must have scanner
hardware connected to it. The scanner hardware does the scanning, and the
scanner software does the image-making. Therefore, assuming that the user's
machine has a scanner attached to it, the user scans some image, and saves
it as a file to their machine. The user can then upload the file as he/she
would upload any file from their machine via a web page.
