* Class ProductImageLabel - class to display Product images

* This class queries the ProductImage table for an image associated with the given

* Product - it returns a QControl that displays the image. If no image is found it

* defaults to showing "default_product.png". The default size is Small and height
|
|
* and width are either set from the ProductImage if possible or left unspecified.
|

*
|
|
* All attributes except Product Id can be manually set - ProductId must be passed

* to the constructor
