[Zope] TextImage , PIL installation troubles

Hi folks! I've been trying to install TextImage for a while now, but apparently my PIL setup is wrong. I can see TextImage in my Products-list, but it only displays the following error-message: Traceback (innermost last): File "/var/zope/lib/python/OFS/Application.py", line 397, in import_products product=__import__(pname, global_dict, global_dict, silly) File "/var/zope/lib/python/Products/TextImage/__init__.py", line 5, in ? import TextImage File "/var/zope/lib/python/Products/TextImage/TextImage.py", line 12, in ? import PIL.Image ImportError: No module named PIL.Image Can anyone help me with some advice on setting up PIL properly? Thanx Walter
