[Zope] How to stop users uploading large images

[Steve Alexander]

Hi Folks,

I want to allow ordinary, low-privalidged but non-anonymous users of my
site to upload small images.

I can use PIL to scale images that are slightly too large.  However, I
want to stop users abusing the system by uploading 100MB images to see
if it will crash the system.

What is the best way of doing this?

Can I modify the _read_data() method of lib/python/OFS/Image.py to read
some kind of maximum-size attribute, and abort uploads that exceed that
size?


Alternatively, perhaps this is something I don't need to worry about.
Maybe the ZODB has a graceful failure mode on extra-large uploads.
