Do you have to store the images in the database? If you are not familiar with it FILESTREAM may be a better alternative. Take a look at BOL here. Depending on your usage the performance is likely much better with this type of approach.

If you must store your images in the database you will need to use a program outside of sql to insert your images. For example in .NET you read your image in a byte array and pass that array as your insert parameter. The filename is just a string so you can handle that like any other varchar.

As Sean says, FILESTREAM is an option, as is storing just the path in SQL Server and keeping the images themselves in the file system. Storing images in the database is another option (particularly if they are around 256KB each or less). If you choose this option, there is a way to add image data directly in T-SQL:

CREATE TABLE dbo.ImageTest

(

image_id integer IDENTITY PRIMARY KEY,

file_path nvarchar(260),

name nvarchar(30),

picture varbinary(max) NOT NULL

)

GO

INSERT dbo.ImageTest

(file_path, name, picture)

SELECT

N'C:\Users\Paul White\Pictures',

N'asterix.jpg',

stream.picture

FROM OPENROWSET

(

BULK N'C:\Users\Paul White\Pictures\asterix.jpg',

SINGLE_BLOB

) AS stream (picture);

GO

SELECT * FROM dbo.ImageTest AS it

If you are looking for a way to also read the contents of a file directory from SQL Server, you could use xp_cmdshell. Another way is to use a SQL CLR function or procedure, see List Directory Contents[/url] or use a pre-built library like the one here: http://nclsqlclrfile.codeplex.com/

This demonstrates loading all the jpeg image files in a directory:

-- Find the files

DECLARE @Files TABLE (name nvarchar(260) UNIQUE)

INSERT @Files (name)

EXECUTE master..xp_cmdshell

-- Change this

'dir /A-D /B /ON "C:\Users\Paul White\Pictures"'

-- Load the image data into the database

DECLARE

@directory nvarchar(260),

@name nvarchar(260),

@sql nvarchar(max);

-- Change this

SET @directory =

N'C:\Users\Paul White\Pictures';

DECLARE cur_Files

INSENSITIVE CURSOR FOR

SELECT f.name

FROM @Files AS f

WHERE f.name IS NOT NULL

FOR READ ONLY;

OPEN cur_Files;

SET NOCOUNT ON;

-- Load each image using dynamic SQL

WHILE (1=1)

BEGIN

FETCH NEXT FROM cur_Files INTO @name;

IF @@FETCH_STATUS = -1 BREAK;

SET @sql =

N'

INSERT dbo.ImageTest

(file_path, name, picture)

SELECT

N''' + @directory + ''',

N''' + @name + ''',

stream.picture

FROM OPENROWSET

(

BULK N''' + @directory + '\' + @name + N''',

SINGLE_BLOB

) AS stream (picture);

';

-- Show progress

RAISERROR ('Loading %s...', 0, 1, @name) WITH NOWAIT;

EXECUTE (@sql);

END;

CLOSE cur_Files; DEALLOCATE cur_Files;
