Why not just pass it on the URL ?

Where do you store them ?

What are you writing this for ? Is it for your own study ? Will it ever be used by anyone ?

im storing in sql server. this is used for my project...

OK, so you're writing it for yourself, or for someone to use ? Why not just pass the id of the image back to the main page then and load it from there ?

The image is associated with the user, right ? So, just write a http handler that takes the id of the image or the user on the query string, looks up the data and returns it. Make this the URL for your image.

I'm not sure why you're asking me for advice, as you appear to, in every step, doing the opposite of what I've suggested. Filling your session with all this data is going to affect performance.

can we display the thumbnail of image before inserting into database....

Christian Graus

Why would you want to ? What is it that you're trying to do ? If you'd answer this question it might help me make a recommendation.

i want to display the uploaded image once i browse through fileupload control.. but before it is saved in database to check the image uploaded correctly or not..

Christian Graus

You can't do that, because until it exists somewhere on your system, you can't send it back to the client. To send it back as a byte stream requires a seperate page or HTTP handler. It's just not possible.

using http handler im getting image to a page.. im unable to get all the three images... only 1st image is displayed...

//SqlCommand select stmt "select image1,image2,image3 from reviews11 where
// staffid=" + staffid
SqlDataReader dr = command.ExecuteReader();
dr.Read();

        context.Response.BinaryWrite((Byte\[\])dr\[0\]);
        cnn.Close();
        context.Response.End();

//another page
Image1.ImageUrl = "handler3.ashx?staffID=" +
Session["staffid"].ToString();
