image name

[Marix]

In my web project I need to show pictures using datalist. So when I set image source to let's say src='GetPicture.aspx?id=[id]' everything works fine, but when someone wants to save that picture it being saved as GetPicture.aspx, so user has to manually rename it afterwards to something.jpg. Is there a way to tell image name and extension? Thank you

Hi there, You simply use the filename parameter of the Content-Disposition header field to suggest a filename for the image. The sample code in the GetPicture.aspx is simple like this:

private void Page_Load(object sender, System.EventArgs e)
{
Response.Clear();

    byte\[\] bytes = GetImageContent();
                   
    Response.AddHeader("Content-Disposition", "filename=myphoto.jpg");
    Response.OutputStream.Write(bytes, 0, bytes.Length);
    Response.End();

}

When you right click on the image and select Save Picture As..., the filename myphoto.jpg will appear in the Save Picture dialog box. For more information, see Content-Disposition header field[^].
