CREATE TABLE [dbo].[tbl_photo_gallery](

[image_id_int] [int] IDENTITY(1,1) NOT NULL,

[image_caption_vchr] [varchar](100) NULL,

[image_path_vchr] [varchar](200) NOT NULL,

[photo_cat_id_int] [int] NOT NULL,

[posted_by_vchr] [varchar](45) NOT NULL,

CONSTRAINT [PK_tbl_photo_gallary_1] PRIMARY KEY CLUSTERED

(

[image_id_int] ASC

)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY]

now i wanna to get a randomly selected image_path_vchr(image path) from each photo_cat_id_int(category)
