display images without having them on the disk?

[Yoramo]

Hello

is it possible to display images on a ASPX without having them on the disk
of the server ?

I have images in a DB and whould like to display them on a web page. writing
them to disk seems very costly.

is it posible to create them in memory and some how give them to the client
to display?

thanks in advance
Yoramo.

Re: display images without having them on the disk?

hi,you can do it just like the following example.

private void Page_Load(objec t sender, System.EventArg s e)
{
SqlConnection mycon = new SqlConnection(" your connection string");
mycon.Open();

int liid = int.Parse(Reque st.QueryString["id"]);
string sqlText = "SELECT img_name, img_data, img_contenttype FROM image1
where id="+liid;
SqlCommand MyCommand = new SqlCommand (sqlText, mycon);
SqlDataReader dr =MyCommand.Exec uteReader();
if(dr.Read())
{
Response.Conten tType = (dr["img_contenttyp e"].ToString());
Response.Binary Write((byte[])dr["img_data"]);
}
mycon.Close();
}

He already did. There is no Template HTML. It simply sends an image. You
include a reference to that page as the URL for an image tag in another
page.
