<updated answer="">
Set a flag saying update = True when user is going to update the fields.
Check for this flag value, if it is True, disable file upload control and while sending updated values to database, do not send the value image. Only send those fields which can be updated.

On Page lOad fetch UserPic on behalf of session and store in Viewstate
