  • Hi,

    Try these steps:

    1.Create a WCF service on the server.
    2.Consume it on the silverlight client.
    3.Call service method to send an image to the server.
    4.Save it on the server with custom logic.

    You could refer to link below,Uploading multiple files with Silverlight:
