Uploaded images aren't shown in view/ aren't resized
An image uploaded in an Archetypes-based object shows only up in the 'Edit' form (in original size) and do not show up (resized) in the 'View'.
You need PIL (python imaging library) or ImageMagick installed properly on your Zope's host operating system.
Solution:
You can download PIL (or use the version delivered with your OS) and make it available to the Python-Installation your Zope uses.
Or you can download ImageMagick (or use the version delivered with your OS) and install it in a way your Zope can access it.

But, the Image object doesn't seem to use it. I only get the full-size images. The resized images aren't there.
