[Zope] crearing a custom ZClass with images

Me again... fiddling with my first ZClass. I will be needing a ZClass to manage biographical data. It should be able to hold text info (a finit set of strings and texts) and images (any number). I'm thinking of creating a Biography Zclass that inherits from CatalogAware, ObjectModel and Folder. Text info will be instance variables; images would simply be placed "in" the Biography instance as independant Images objects. A few class methods would deal with the contents of the Biography so that it is as transparent as possible. Before i dig too deep into this, am i on the right track? Alex.
