Question

I am looking to fileupload a picture jpeg,gif,etc into an SQL database on an updateprofilepicture page. Then on the profile page, I want to retrieve the image from an sql database and have it show up in an Asp:Image control. I have much code trying to do this and it doesn’t work. The table contains a column of type Image.

As Joel mentioned you should use an HttpHandler or a page to display the image. Here is a sample code to output image (Image.ashx) :

// ProcessRequest method of Image.ashx long imageId = Convert.ToInt64(Request.QueryString['ImageId']);  using (var conn = new SqlConnection(connectionString)) using (var command = new SqlCommand(     'SELECT ImageFile FROM ImageTable WHERE ImageId = @ImageID', conn)) {     command.Parameters.Add('@ImageID', SqlDbType.Int).Value = imageId;     conn.Open();      Response.ContentType = 'image/gif';     Response.BinaryWrite((byte[]) command.ExecuteScalar()); } 

and then use image in your page as :

  <asp:Image id='Image1' runat='server' ImageUrl='Image.ashx?ImageID=12'/>
