why you use a stored procedure for that??
well the first i will check is the datatype of the columns that you are inserting are binary,and the review if the data obtained is well formed for parsing to a binary field. :P

Add a stored procedure for insert a binary type field.

SQL

CREATE PROCEDURE sp_InsertBinary
(@BinaryArray Binary)
AS
BEGIN
	INSERT INTO TABLE_OF_BINARY_FIELD VALUES(@BinaryArray)
END

Secondly, ensure that the Datatype that you are sending in your DataLayer are Binary, like this:

C#

SqlParameter sqlParam = new SqlParameter();
       sqlParam.DbType = System.Data.SqlDbType.Binary;
       sqlParam.Value = yourBinaryArray;

don't forget to add your parameter to your sqlcommand and execute them.
