Download into MS Word document including images

[gerard.buskermolen]

Hello world,

I have an ASP.NET application that returns HTML to the browser that
should be read by MS Word.
To do this I set

Response.ContentType = ContentType.Word
Response.AddHeader("Content-Disposition", "Report.doc")

and render the HTML.
The browser (IE6.0) shows a dialog box which enables the user to Open
the HTML in Word or save the report to disk.

So far so good.

But now I want to include a number of images into the Word document.
These images are created on the fly during the generation of the HTML
(so they are not available in a file on the webserver. In fact, for
each image I've got an System.IO.Stream representing the image).

I know that there is something like

<img src="data:image/gif;base64,iVBORw0KG....." >

to include the image itself in the HTML. This construction is
understood by Firefox, but not by IE or MS Word.

So I think I should download the images as seperate files. A
subdirectory
in de Temporary Internet Files should be created, the images should be
saved in this subdirectory and the HTML should refer to those images,
for example <img src="MyDir\MyImageFile.jgp">.

Does anyone know how to do this or have any other suggestion?

Thanks in advance,
Gerard
