p.a.imaging scaling

Hi all,

When using "scale.scale('image', width=1200, height=800,
direction='down').tag()" in a template is the image created on the fly? and
more important, is this done for every single call? or is the scaled image
stored in blob?

<img tal:define="scale context/@@images"
     tal:replace="structure python: scale.scale('image',
                  width=1200, height=800, direction='down').tag()" />

Second question, when using a direct url, so i don't need to get the object
when looping brains:

<img tal:attributes="src string:${brain/getUrl}/@@images/image/preview;
alt: view/Title" />

Is the preview image already created and saved as blob, or made on view and
this way it still calls the object?

Last question:
Is it possible to create a new scale having direction 'down' or 'up'
setting, so i can call this scaled image directly by url? When creating a
new scale in propertiestool.xml you cannot select any directions and image
format is respected.

Regards,
