No no I don't know why that doesn't work because it really should but I'll
give you a snippet that DOES work. Oddly enough, it works by NOT specifying
the content type. Bizzare eh? Also, it works fine as URL in address bar or
as img src=.

Here ya go free of charge. Sorry if it looks like html to you - you get
what you pay for :) Insert it using paste as html or something and it
should look fine. This code shows a thumbnail picture from a sql database
using a simple select thumbnail from pictures query. If there is no data,
it draws a black box instead. Notice that I had to comment out the mime
type in order to get it to work:

OleDbConnection myConn = new
OleDbConnection(ConfigurationSettings.AppSettings["OLEDBDSN"].ToString());

OleDbCommand myCmd = new OleDbCommand(sqlText, myConn);

OleDbDataReader dr = null;


//open the database and get a datareader

try

{

myConn.Open();

dr = myCmd.ExecuteReader();


if ( dr.Read() ) // Check to make sure we loaded a user record

{

// Response.ContentType = "image/jpeg";

Response.BinaryWrite( (byte[]) dr["Thumbnail"] );

}

else

{

// Draw the .JPG

//------------------------------------------------------

// Create a bitmap that measures 130 pixels square

Bitmap bitmap = new Bitmap (130, 130,

PixelFormat.Format32bppArgb);

// Create a Graphics object for drawing to the bitmap

Graphics g = Graphics.FromImage (bitmap);

// TODO: Use Graphics methods to draw the image

// Set the response's content type to image/jpeg

// Response.ContentType = "image/jpeg";

// Write the image to the HTTP response

bitmap.Save (Response.OutputStream, ImageFormat.Jpeg);

// Clean up before returning

bitmap.Dispose ();

g.Dispose ();

//------------------------------------------------------

} // Draw the image

} // try

catch(Exception myException)

{

Trace.Write("Oops. The error: " + myException.Message);

} // catch

finally

{ // Do this no matter what

// Close the database connenction

myConn.Close();

}

} // Done trying to load image from database
