Server.MapPath returns a file path to the image. If you look that the
renderes html in you web page, you'll see that you end up with something
like "c:\inetpub\wwwroot\images\roomscenes\3245_ss.jpg"
you'll want to make sure that ou're returning a relative url to the image.

Also if you do a MapPath of "\images" then it maps the path from your web
root, as opposed to your web application's root (i.e. http://server/images
versus http://server/MyApp/images)


Side Note...
you can use a tilde "~" in urls with asp.net apps to denote your
appplication's root url, so you could use something like...

<asp:Image ImageUrl='<%#
"~\images\roomscenes\"+DataBinder.Eval(Container.DataItem,
"PartNo")+"_ss.jpg") %>' runat="server" ID="Image1" />

Assuming that "images" is a directory located inside your application (e.g.
http://server/myapp/images)
