[Seaside] MAPictureDescription missing from Magritte???

Hi John,

MAFileDescription used to display the uploaded image in earlier
versions. I changed that to simply put a link for various reasons.
There are many different ways to display a picture, sometimes
applications need to add special tooltips, make them clickable or
resize and convert them to a special format.

That would be a possibility, if you need some sophisticated meta
capabilities on pictures. For me I mostly went with the

      ^ MAFileDescription new
         accessor: #picture;
         addCondition: [ :file | file isImage ];
         componentClass: MAPictureComponent;

The condition ensures that only images can be uploaded. The component
class changes the default view to a custom subclass of MAFileComponent
that automatically resizes and displays the picture.

If you want to contribute an MAPictureComponent I am sure some people
would be interested to use such a plugin. However I doubt that it is
possible to write it in a platform independent way, so that it could
be part of Magritte-Seaside.

Btw, there is a special mailing-list for Magritte, see
