Answer 1

You should pass relative address to Server.MapPath

It should be something like: ~\Project1\Project1\Images\ instead of the physical path:
C:\Users\Mayer\Documents\Visual Studio 2010\Projects\Project1\Project1\Images\

The MapPath method maps the specified relative or virtual path to the corresponding physical directory on the server.
