getting wrong images appear using ASP AJAX slideshow extender which dont belong to model selected?

hi,
I though this problem was solved but I still get random images appearing in my slideshow which dont belong to the
userId in the query string which is the SQL parameter.

I have a database of say 500 models.

There is a Models Table
ModelId (guid)
FirstName nvarchar
LastName nvarchar
Skills  nvarchar
etc

I have placed the slideshow extender on my Model.aspx page like so

                                      <cc1:SlideShowExtender ID="slideshowextend1"                 TargetControlID="imgShowImage"        &n ...
