Try to do this in the following way.
1-Store image in application's local folder as per your desired hierarchy.
2-Store image name in the db.
TO VIEW the upload images, do the following.
Get the images name from the db and use like below to show the images.
<asp:Image ID="imgUploaded" Height="100px" Width="100px" runat="server" data-lightbox="img1" ImageUrl='<%#"~/Images/"+Eval("ImageName") %>' />
EXPLAINATION: Image URL consist of half hard coded path and image name from the datasource(query returned data i.e in EVAL()).
Hope it will help you. For any further query, comment or objection, Most welcomed. :)
