[Zope] adding objects to a ZCatalog

[Tom Von Lahndorff]

Hi,

I have a folder called "images" and a form that to add images to that 
folder. The form called an external method (../images/addImage) that 
references a python script, the one I sent earlier, that creates 4 
versions of the images in 4 sizes and places them in the "images" 
folder. Also in the "images" folder I have a ZCatalog called 
"ImageData". I'm trying to add a line to the python script to 
automatically catalog any images that are added to the "images" folder. 
I tried "ImageData.manage_catalogObject..." but I kept getting back: 
NameError: global name 'ImageData' is not defined. Any advice? Thanks.

Tom
