Is 0x really stored in the database?
Do you store the data as a string?

No I set datatype as image and it stored like this hexagonal
0x53797374656D2E44726177696E672E4269746D6170

Solution 1

Stored Images in Local Folder Name (Images) and Stored Images Name in Database

imgPic.src = string.Concat("Images/", Convert.ToString(objRow["ImagesName"]));

Hi Tarun,
U r fetching data from database correctly.
I think u have saved image in wrong format plz try below code
write image to byte array

C#

FileStream fs = new FileStream(@"C:\Users\ku102\Pictures\bitmap\usertile36.bmp", FileMode.Open, FileAccess.Read);
byte[] imgbnry = new byte[fs.Length];
fs.Read(imgbnry, 0, imgbnry.Length);
fs.Close();

pass byte array to backend for saving

C#

cmd.Parameters.Add("@img", System.Data.SqlDbType.Image);
cmd.Parameters["@img"].Value= imgbnry;
cmd.ExecuteNonQuery();

good luck ;-)
