Hello... I have used this code with Image datatype in Sql server 2008,2012. Varbinary was working only in Sql 2005. Don't think it's problem using varbinary. Now i"ll try and will respond u if i succeed.

Yeah...It's working. In my code change SqlDbType.Image to SqlDbType.VarBinary. It's working. By the way Thanks for your question.
