The uploading of the image file is performed by ASP.NET 4.0 Client Callbacks. If you are not familiar with client callbacks then I suggest that you take a look at ASP.Net AJAX Control Toolkit AsyncFileUpload Control without page refresh or PostBack in ASP.Net Web Page or ASP.Net AJAX Update Panel. The callback is fired as soon as the file is selected by the user using the file field control.
