Struts2 multiple files upload with a twist

Let's say I have the following model classes

package com.example.model;

public class Product {
    private int productId;
    private String productName;

    //Getters and setters

}


package com.example.model;

public class ImageTypes {
    private int imageTypeId;
    private String imageLocation;
    private String description;

    public ImageTypes(int id, String loc, String desc){
     imageTypeId = id;
     imageLocation = loc;
     description = desc;
    }

    //Getters and setters
}

package com.example.model;

public class ProductImages {
    private int productImageId;
    private int productId;
    private int imageTypeId;
    private String imageName;

    //Getters and setters
}

My action is as follows

public class ProductAction extends ActionSupport implements ModelDriven<Product>{

private Product product = new Product(); 
private List<ImageTypes> imgTypeList;
private List<File> imageFiles;
private List<String> imageFilesFileName;
private ImageTypesDAO imageTypesDAO = new ImageTypesDAO();

@Override
public String execute() throws Exception {
 imgTypeList = imageTypesDAO.getImageTypes();
 return super.execute();
}
    //Getters and setters
}

DAO

public class ImageTypesDAO {

    public List<ImageTypes> getImageTypes(){
     List<ImageTypes> l = new ArrayList<ImageTypes>();

     l.add(new ImageTypes(1, "images/small", "Small"));
     l.add(new ImageTypes(2, "images/large", "Large"));
     l.add(new ImageTypes(3, "images/thumb", "Thumb"));

     return l;

    }
}

 </s:iterator>
 <s:submit name="Save" align="left" cssStyle="font-size: 15px"></s:submit>
</s:form>

</body>
</html>

The images uploaded by the user has to go to their respective directories in the server (eg. file in 'small' has to go to 'images/small', 'large' to 'images/large'.. ). Now the problem is how can I associate the imageTypeId with each file ? I was able to solve this with some javascript trickery and hidden elements but is there any proper way to let struts2 handle this ?
