Contents of an oebjct

Hi All,
I was wondering what contents would be considered good form inside an
object?
Would it be considered good form to hold (say) an image that is
representative of the object within the object?
I ask this question as it seems to step over the line of "presentation"
and "business" relationships.
Thanks.

Is the image in question actual data? E.g. if the object is TProduct, is the

image of the product, stored along with other product data and updateable
the same way? If so then it belongs with the object as much as any other
data.
If the image is *only* for presentation, e.g. an image placed on a button
used to get to the Products form, then it does *not* belong in the object,
it belongs solely in the GUI layer.
