[Archetypes-users] Accessible Image

[dvd <dv...@gn...>]

Hi all,=20

I'm wondering what is the best way to code an AccessibleImage data type
in Plone. For Accessible Image I mean a standard image with alternative
presentation (obviously a textual one, but maybe an audio should be
fine)

I think that the best way is to create a new Field and Widgets Objects
so I can use this AccessibleImage in every schema.

What do you think? Is there a tutorial or a good piece of code (like the
RichDocument) to learn about making custom Field?

thank you
