How Can i insert an image in this form whose button submit code is as follows.

protected void btn_add_Click(object sender, EventArgs e)
   {

       if (btn_add.Text == "Submit")
       {
           BracketAccessoriesEntity.BracketSuspensionType = Convert.ToString(txt_BracketSuspensionType.Text.Trim());
           BracketAccessoriesEntity.PoleTypeID = Convert.ToInt64(dd_PoleTypeID.SelectedValue.Trim());

           BracketAccessoriesEntity.Status = chk_Active.Checked;
           System.Collections.Hashtable ht = (System.Collections.Hashtable)Session["UserDetails"];
           Int64 UsrId = (Int64)ht["UserID"];
           BracketAccessoriesEntity.CreatedBy = UsrId; Convert.ToInt32(Convert.ToString(Session["UserID"]).Trim());
           BracketAccessoriesEntity.CreatedOn = (DateTime.Now);


           try
           {
               string result = logic.InsertData(BracketAccessoriesEntity);
               if (result == "SUCCESS")
               {
                   string jScript = "<script>alert ('" + "Record Inserted Successfully" + "')</script>";
                   ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "starScript", jScript, false);
                   clear();

                   //after insert is successful bind the grid again to show all data
                   BindGrid();
               }
               else
               {
                   string jScript = "<script>alert ('" + "Error in insertion. " + result.Replace("'", " ") + "')</script>";
                   ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "starScript", jScript, false);
               }
           }
           catch (Exception ex)
           {
               string jScript = "<script>alert ('" + ex.Message.Replace("'", " ") + "')</script>";
               ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "starScript", jScript, false);
           }
       }

This is the entities

 public class BracketAccessoriesEntities
    {
        public long AccessoryID;
        public string BracketSuspensionType;
        public bool Status;
        public long CreatedBy;
        public DateTime CreatedOn;
        public long UpdatedBy;
        public DateTime UpdatedOn;
        public long PoleTypeID;
        public long ImagePath;


    }
}

And this is the bussiness logic

public string InsertData(BracketAccessoriesEntities BracketAccessoriesEntity)
       {

           ISingleResult<SP_INSERT_INTO_BRACKET_ACCESSORIES_MSTResult> ds = context.SP_INSERT_INTO_BRACKET_ACCESSORIES_MST(BracketAccessoriesEntity.BracketSuspensionType, BracketAccessoriesEntity.Status, BracketAccessoriesEntity.CreatedBy, BracketAccessoriesEntity.CreatedOn, BracketAccessoriesEntity.PoleTypeID);

           string strResult = "ERROR";

           foreach (SP_INSERT_INTO_BRACKET_ACCESSORIES_MSTResult row in ds)
           {
               strResult = row.STATUS;
               if (strResult == "ERROR")
               {
                   strResult = row.ERROR_MESSAGE;
               }

           }

           return strResult;
       }

I have created an imagepath field in the table named "ImagePath". I want to store image path in database and image in a folder. But I don't know how to do it using entity framework.

Below is the stored procedure

ALTER PROCEDURE [dbo].[SP_INSERT_INTO_BRACKET_ACCESSORIES_MST]
	@BracketSuspensionType varchar(45) ,
	@Status bit ,
	@CreatedBy bigint ,
	@CreatedOn datetime ,
	@PoleTypeID bigint,
	@ImagePath image
AS
BEGIN
	SET NOCOUNT ON;
    BEGIN TRY
     --BEGIN TRANSACTION TransInsertBracketAccessories
		INSERT INTO dbo.DEF_BRACKET_ACCESSORIES_MST (/*Insert Statement*/
		[BracketSuspensionType]
      ,[Status]
      ,[CreatedBy]
      ,[CreatedOn]
      ,[PoleTypeID]
	  ,[ImagePath]
		) VALUES(
			@BracketSuspensionType
			,@Status
			,@CreatedBy
			,@CreatedOn
			,@PoleTypeID
			,@ImagePath
		)
	 /*Returns Success as result*/
	 SELECT 'SUCCESS' AS [STATUS],ERROR_LINE() [ERROR_LINE],ERROR_MESSAGE() [ERROR_MESSAGE],ERROR_NUMBER() [ERROR_NUMBER],ERROR_PROCEDURE() [ERROR_PROCEDURE],ERROR_SEVERITY() [ERROR_SEVERITY],ERROR_STATE() [ERROR_STATE],@@TRANCOUNT [TRANCOUNT],@@ROWCOUNT [ROWCOUNT]
     --COMMIT TRANSACTION TransInsertBracketAccessories
    END TRY
    BEGIN CATCH
	 --ROLLBACK TRANSACTION TransInsertBracketAccessories 
	 /*Returns Error*/
     SELECT  'ERROR' AS [STATUS],ERROR_LINE() [ERROR_LINE],ERROR_MESSAGE() [ERROR_MESSAGE],ERROR_NUMBER() [ERROR_NUMBER],ERROR_PROCEDURE() [ERROR_PROCEDURE],ERROR_SEVERITY() [ERROR_SEVERITY],ERROR_STATE() [ERROR_STATE],@@TRANCOUNT [TRANCOUNT],@@ROWCOUNT [ROWCOUNT]
    END CATCH
	SET NOCOUNT OFF;
END
