[Zope] python/ retrieving JPG from folder

[VIGNAUX Philippe]

Thanks for your proposal of the "photo and photo folder" product.
I'll surely use it as I don't see any other possibility.

But the goal was to know the bloody way to get the content of a picture
and provide it as a parameter to a method.

I can't believe it's not possible within Python as I'm so close to the
solution !

for item in context.remote.fileValues():
    context.makethumbnail(??item??)

nb: item.id gives the name of the picture. I need to reach the content,
i mean the picture itself.

Hi
I asking myself if you need a product that creates thumbnails
