how to display a image before showing binary content

[Holysmoke]

Hi,

I writing a binary content from a file (which may be hefty) in asp.net page.
But I would like to show something like work in progress Icon/image

But it is never shown on the browser

I cannot understand how to do that.

Here is my codice

Response.Write("<img src=""Immagini/workinprogress.gif""
border=""0"" />")
Response.BinaryWrite(myBinaryContent)
Response.Flush()

P.S : myBinaryContent is of content type html

I appreciate your help,

TIA,
Holy
