I am using pure asp upload to upload images to a folder. When I do not upload a page, I want an alternate image to display. I am using the following code:

If IsNull(rsArticle.Fields.Item("Image_Blob".Value) = True Or IsEmpty(rsArticle.Fields.Item("Image_Blob".Value) = True Then
Response.Write"<img src=""images/transparent.gif"">"
Else %>
<img src="../../../../database/upload/<%=(rsArticle.Fields.Item("Image_Blob".Value)%>"><% End If %>

This only works if the value in the database is "null". Pure asp upload apparently changes the value to a zero length string when nothing is uploaded to that field. How do I take care of this problem. I want a transparent gif displayed if there is not a file uploaded.

Thanks
