How to get Image value in SP

Hi,
I have a SP that needs to get the value of image field (the data type is
image).
But I can't declare a image data type variable, it response:
The text, ntext, and image data types are invalid for local variables.
So, How can I get image value in Store Procedure?
Thanks for help!
AngiImage (and text/ntext) data types cannot be declared as local variables.
These are mostly intended to be transferred to/from application code
directly.
What do you plan to do with the image value in the proc? You can use
SUBSTRING to assign 'chunks' of the image value to a local varbinary
variable.

Hope this helps.

I use VARBINARY and it's work!
What do you plan to do with the image value in the proc?
I assign a value to SP and want to response correct image code embeded on
SQL.
Then use the SQL to present image and other information on RS report!
Last, I use Function instead of Store Procedure!

application, you don't need a variable. See the examples below.
CREATE PROC dbo.GetImageAsResult
@.ImageID int
AS
SELECT MyImage
FROM dbo.MyTable
WHERE ImageID =@.ImageID
GO
CREATE PROC dbo.GetImageAsOutputParameter
@.ImageID int,
@.Image image OUTPUT
AS
SELECT @.Image = MyImage
FROM dbo.MyTable
WHERE ImageID =@.ImageID
GO
Hope this helps.
