I uploaded an image, but plone doesn't display any preview, just the full-sized image.
You may be missing the Python Image Library. Check your Zope event.log file for messages like:
Warning: no Python Imaging Libraries (PIL) found. Archetypes based ImageField's don't scale if neccessary. PIL not found. Plone needs PIL 1.1.5 or newer to scale images. Please download it from http://www.pythonware.com/products/pil/ or http://effbot.org/downloads/#Imaging
As the message says, PIL is required for image scaling. It's available from http://www.pythonware.com/products/pil/ or http://effbot.org/downloads/#Imaging . It may also be available from your favorite package system, but make sure that you get version 1.1.5 or newer; the package may be called something like "python-imaging".
Even if you have PIL installed, it may not have jpeg support if for some reason libjpeg wasn't found when PIL was being configured. You may find an error like:
IOError: decoder jpeg not available
Refer to the error reference for suggestions to fix this problem.
