Hi all,

I got quite a lot further now. Here's the script I have so far:

import PIL.Image import os.path import cStringIO

def MakeThumb(self, image, width, height): oriImage = getattr(self, image) oriFile = cStringIO.StringIO(oriImage.data) image = PIL.Image.open(oriFile) image.thumbnail((width, height)) thumbnailImage = StringIO() image.save(thumbnailImage, "JPEG") thumbnailImage.seek(0) return thumbnailImage.getvalue()

this all works find if you use it as:

<dtml-var "PHTO_MakeThumb('AB_action_inbox.jpg', 160, 120)">

As soon as you want to do something like:

<dtml-var "PHTO_MakeThumb('/images/AB_action_inbox.jpg', 160, 120)">

you get an AttributeError. Does anybody has a way around this?

Try it with images.PHTO_MakeThumb('AB_action_inbox.jpg',160,120) if you use getattr, you ask your context about '/images/AB_action_inbox.jpg' but your context does not have an attribute with this name, it has an attribute (or acquires an attribute) 'images' which is another object which has the attribute 'AB_action_inbox.jpg' Mayby its even better, if you make a Product, derive your zclass from Image and make it a method of your new image class, then you can even refer to it like this: <dtml-var expr="images.AB_action_inbox.PHTO_MakeThumb()"> (only if you dont name your images with extension. This yould make it more complicated: <dtml-var expr="images['AB_action_inbox'].PHTO_MakeThumb()"> HTH Tino Wildenhain HTH Tino Wildenhain
