You have several options:
a) Create a virtual directory (ie:pictures) in the IIS inside your application so it points to c:\picture, and then your links would be like this "~/pictures/yourpicture.ext
b) Create a page or similar mechanism that recieves a name of an image and then you serve it using the function Response.TransmitFie(filename)
If it was possible I would use a)
Hope this helps
