VB.NET set embedded object src to byte array? dynamically set src value

Question

I am trying to dynamically set the src attribute inside of embed tags which is in turn inside object tags:

<object width=700 height=700>
<embed src=__bytearraycontents___ type="image/vnd.djvu" width="700" height="700" />
</object>

When I obtain the byte array and save the image file to test.djvu on my harddrive and then set the src to this, it works fine. My problem is that I don't want to have to write the image to the hard drive, I want the src to be set to the Byte array straight away. Can anyone advise?

Thanks, C

Set the src attribute to a page that returns .djvu files. The page can be an .aspx or a HTTP Handler. Pass in your unique identifier in the query string in the url in the src. On your document serving page, make sure the Response.ContentType is "image/x.djvu".

Example:

<embed src="YourPageThatServesUpDocuments.aspx?DocumentID=1" type="image/vnd.djvu" width="700" height="700" />

Hypothetical Crude Example of YourPageThatServesUpDocuments.aspx's Page Load:

Response.ContentType = "image/x.djvu"
'Where GetByteArrayByDocumentID is the code that gets your byte array.
Response.BinaryWrite(GetByteArrayByDocumentID(Request.QueryString("DocumentID")))
