Form that we can't necessarily tell.
However, I would open the page in the browser, and either right click on it to "View Source", (IE) or Right click the image and "Insepect element" (Chrome) - FF will have similar.
You can then look at what the HTML is trying to display for the image in terms of the url. I suspect that it will be a Server based HDD address, which is of no use what so ever to a Client based browser...

Have a look at this: A generic Image-From-DB class for ASP.NET[^] - it may not cover your needs exactly since it assumes the image is actually stored in the DB, but it should be easy for you to modify to fit your circumstances.
